Answer:
Kinases are catalysts or enzyme that regulates the organic action of proteins by adding phosphate groups and cause the conformation change to a dormant to a functioning type of the protein.
Cyclins bind to CDK or cyclin dependent kinases to regulate by switching on and off the progression of the cell through cell cycle. At the G2 mitosis border , a CDK 1 combines with another cyclin ( B) , phosphorylation (adding of phosphate group) occurs bringing about a series of changes in the nuclear membrane via cytoskeleton, caldesmon and histone H1. CDK 4 binds to cyclin D , moving cells from G1 to S.

Arrange the isotopes of oxygen and carbon in order of decreasing number of neutrons.
Rank the isotopes from most o fewest neutrons. To rank items as equivalent, overlap them.
Answers
Answer:
C-12 > C-13 > C-14,O-16 > C-16,O-18
Explanation:
Generally, isotopes are described as atoms of the same elements with the same atomic number but different number of neutrons.
Hence,
For O-18, oxygen has an atomic number of 8 and neutron number of 10.
For C-14, carbon has an atomic number of 6 and neutron number of 8.
For C-13, carbon has an atomic number of 6 and neutron number of 7.
For C-16, carbon has an atomic number of 6 and neutron number of 10.
For carbon 12, carbon has an atomic number of 6 and neutron number of 6.
For O-16, oxygen has an atomic number of 8 and neutron number of 8.
Hence the rank from the fewest neutrons would be C-12>C-13>C-14,O-16>C-16,O-18
In humans, oculocutaneous (OCA) albinism is a collection of autosomal recessive disorders characterized by an absence of the pigment melanin in skin, hair, and eyes. That is, normal pigmentation (A) is dominant over albinism (a). For this question, assume it is a single gene with two alleles. Assume it is a single gene with two alleles. If two people have normal pigmentation, what possible phenotypes may be observed in their offspring?
Answers
Answer:
The definition of the problem is listed in the explanation segment below.
Explanation:
The parent phenotype is an albino on every one of them. Albino gene seems to be located primarily while it has its whole genotypes in such a recessive state called "aa". When this trait becomes autosomal, it does have an equivalent amount of alleles across both parent members. The gametes including its albino genotypes.⇒ [tex]Mother \ aa\times Father \ aa[/tex]
⇒ [tex]a\times a[/tex]
Genotype including its offspring - albino. Well, all offspring will also have albino phenotypes.So that the above is the right answer.
Fat mobilization is the breakdown of fats in adipose tissue into metabolic products that enter the bloodstream place the steps of fat mobilization in order
Actual Answer:
1) body releases epinephrine
2) epinephrine binds to fat cells in adipose tissue
3) tricylglycerols are hydrolyzed to glycerol & fatty acids
4) metabolic products enter the bloodstream
Answers
Answer:
The complete steps are:
1. Body needs energy for activity
2. body releases epinephrine
3. epinephrine binds to fat cells in adipose tissue
4. triacylglycerols (triglycerides) are hydrolyzed to glycerol and fatty acids
5. Fatty acids transported to tissue
Explanation:
Mobilization of fat is a gluconeogenetic process (a process that sequesters energy from a compound other than carbohydrates), in which fat molecules in the adipose tissues are metabolized for energy production.
The process starts when the body is in an energy-deprived (hypoglycemic) state, leading to the release of glucagon by the pancreas and the release of epinephrine (adrenaline) from the adrenal medulla of the brain.
These hormones activate gluconeogenesis and glycogenolysis (breakdown of glycogen) in the liver, it also activates lipolysis in the muscle cells and liver, as well as inhibiting fatty acid synthesis. This is mediated through the binding of these hormones to specific receptors on the surface of fat cells, leading to the activation of lipases (enzymes catalyzing lipolysis). Lipases catalyze the hydrolysis of triglycerides (common fat in diets) to glycerol and three molecules of free fatty acids. These free fatty acids are released into the blood where they attach to serum albumin; a protein for transporting the hydrophobic fatty acids to the muscle cells where they are taken up and utilized to produce energy and C0₂.
In each of the scenarios, an individual heterozygous for the indicated gene or genes is crossed with an identical heterozygous individual. Predict the number of different phenotypes that would be observed among the progeny of such a cross.

Which of these statements are accurate? Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing ATP. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2–MgATP2– complex are bound. Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. Hexokinase is found in the mitochondrial membrane.
Answers
Answer:
A. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing ATP. True
B. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2–MgATP2– complex are bound. True
C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. True
Explanation:
A. Hexokinase suffers and conformational changes by binding glucose in a reaction that prevents ATP hydrolysis.
B. Hexokinase is an enzyme with two domains that function by binding to the substrate (i.e., glucose). The region linking both protein domains is responsible for the catalytic activity.
C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. During the first stage of glycolysis, the hexokinase transfers one phosphorous group from magnesium-ATP (Mg-ATP) to one hexose molecule, such as fructose, mannose or glucose.
False statements:
- Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. False: In canonical kinases, conserved amino acids bind to divalent metal ions before the transference of the phosphate group to their substrates.
- Hexokinase is found in the mitochondrial membrane. False: Hexokinase is found in the cytosol.
- Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. False: Hexokinase catalyzes the transfer of the terminal phosphate ATP to form glucose 6-phosphate.

What are Viruses?Small infectious agents known as viruses can multiply only in the living cells of other animals. They are composed of genetic material, which can be DNA or RNA, encased in a protein shell called a capsid. Some viruses also have a lipid-based outer coat.
Because they cannot perform metabolic functions on their own and require a host cell to reproduce, viruses are not considered living organisms. They spread infection to various living things including bacteria, plants, animals and people.
A virus replicates its genetic material and forms new viral particles when it infects a host cell using the host cell's machinery. This can lead to the death of the host cell and result in the spread of the virus to other cells of the host.

______ is the process responsible for the situation above. This process can cause DNA to change in many ways. Three such ways are ______, _____, and _____.
Answers
Answer:
Explanation:
Mutation can cause a change in DNA to change in many ways.
Mutation is the sudden change in the genome of an organism that can be heritable from parent by their offspring.
Missense mutation - This occur when a base pair is substituted for by another leading to the formation of an entirely new amino acid.
Nonsense mutation - This occurs when a base pair is substituted for by another leading to the formation of a new amino acid. The new amino acid form therefore send a stop signal to the sequence of amino acid been built.
Insertion or deletion - Insertion mutation inserts new base pair into the sequence changing the number of the DNA base while deletion deletes a base pair changing the number of DNA base from the amino acid sequence.

Explanation:
Because bacteria reproduce quicker and are also in smaller populations, they can evolve quicker because more genes are shared which can be helpful. This is due to natural selection, which will affect bacteria more than mammals because their small populations will make natural selection more significant to be harmed by mutations and allow them to evolve.

The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or insertion mutation. Identify which sentence represents a substitution, which represents a deletion, and which represents an insertion.
Answers
Answer:
The question is incomplete, the complete question has been added as an attachment.
THE DGR AN represents deletion mutation
THE RED ANA TRA N represents insertion mutation
THE FOX WTS RED represents substitution mutation
Explanation:
Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.
An insertion mutation is the addition of one or more nucleotide bases to the sequence.
A substitution mutation is the replacement of one or more nucleotide base in a sequence.
The original sentences were:
1. THE RED ANT RAN
2. THE FOX WAS RED
3. THE DOG RAN
The three sentences that mutated/changed are:
1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.
2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.
3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.

c) Active Activator
d) Active Repressor
NEGATIVE CONTROL
f) Inactive repressor
a) Inactive Activator
b) cAMP
Explanation:
The positive controls are those groups in the experiment whose treatments are expected to confirm previously known results, thereby enabling the comparison of these results with the target group. In this case, both active activators and repressors are able to give results that can be compared with the test group
The negative controls are those experimental groups where no response is expected. In this case, both inactive activators and repressors, and cAMP (which is a secondary messenger in diverse biological processes but is not involved in this pathway), are not expected to produce any measurable response.

Describe the typical principles used to identify topogenic sequences within proteins and how these principles can be used to develop computer algorithms. How does the identification of topogenic sequences lead to prediction of the membrane arrangement of a multipass protein
Answers
Answer:
Topogenic sequences share a series of structural features, and thereby computational algorithms can be used to predict these protein-membrane segments
Explanation:
Topogenic sequences are protein segments formed by alpha-helical transmembrane domains, which are required for the insertion of membrane proteins. These domains share a series of well-defined features: they are composed of segments of about 20 hydrophobic amino-acid residues. In consequence, computational algorithms can be designed to identify protein patterns that fulfill these structural requirements (i.e. segments with a length of 20 residues, hydrophobic level, etc). The models assign a similarity threshold (threshold value) that predict if the similarity level of the protein pattern is good enough to detect a topogenic segment.
