The instructions for making proteins are coded in the (cytoplasm / DNA / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / nucleus).
Answers
Answer:
The instructions for making proteins are coded in the (cytoplasm / DNA / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / nucleus).
Explanation:
The genetic code is contained in DNA, or deoxyribonucleic acid. This is usually the same among most organisms, save some RNA viruses. But in eukaryotes, the DNA is in the nucleus, whereas in prokaryotes the DNA is in the "nucleoid region", or a twisted up section near the middle of the cell.
The instructions for making proteins are coded in the DNA of a cell. In a eukaryotic cell, these instructions are located in the nucleus.
What is DNA?Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for the development, functioning, growth.
it is also involved in reproduction of all known organisms and viruses. Nucleic acids include DNA and ribonucleic acid.
The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins.
These instructions are stored in the nucleus of each of your cells and are distributed across 46 long structures known as chromosomes.
These chromosomes are composed of thousands of shorter DNA segments known as genes.
DNA is a linear molecule made up of four different types of smaller chemical molecules known as nitrogenous bases.
Thus, DNA is involved in coding protein and is usually located in nucleus.

In a particular species of tomato plant, the plants can bear fruits of different colors. Suppose a researcher crosses a homozygous plant that bears white fruit with a different stock of homozygous plant that also bears white fruit. In the F1 generation, all of the fruits are red. Two F1 plants are then crossed and the F2 progeny are examined. The F2 generation contains 219 plants with red fruit and 173 with white fruit.
Required:
a. What are the genotypes of the F2 progeny?
b. What type of epistasis, if any, is present?
1. dominant epistasis
2. duplicate recessive epistasis
3. duplicate dominant epistasis
4. no epistasis
5. recessive epistasis
Answers
Answer:
The genotypes of the F2 progeny are 9/16 A-B-, 3/16 A-bb, 3/16 aaB- and 1/16 aabb.The occurring interaction is duplicate recessive epistasis.Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis". In duplicate recessive epistasis, two genes are involved in the same metabolic path. Two recessive alleles in any of the two loci can suppress or inhibit the phenotype, in this example, tomato color.
Tomatoes that express the absence of color in the fruit have the following genotypes: aa B_, A_bb y aabb. Tomatoes with these genotypes are white, while tomatoes with A_B_ genotypes are red.
Cross 1:
Parental) aaBB x AAbb
Gametes) aB aB Ab Ab
Punnet Square) aB aB
Ab AaBb AaBb
Ab AaBb AaBb
F1) 100% AaBb, red tomatoes
Cross 2:
Parental) AaBb x AaBb
Gametes) AB Ab aB ab
AB Ab aB ab
Punnet Square) AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB Aabb aaBB aaBb
ab AaBb Aabb aaBb aabb
F2) 9/16 A-B-
3/16 A-bb
3/16 aaB-
1/16 aabb
Genotypes A-bb, aaB- and aabb express white or absence of color.
Genotypes A-B- express red color.
We know that in the F2 generation there are 219 plants with red fruit and 173 with white fruit.
The total number of plants is 392 (219 + 173), which is 100% of the F2 generation. So:
392 plants ----------- 100% F2 ---- 16
219 red plants--------56% F2------- 9
173 white plants------44% F2 ------ 7
There is a proportion of 9:7 because of the interaction between the two genes.

This skull belongs to a multituberculate non-therian mammal, Taeniolabis, from the Paleocene. It looks superficially like some rodent skulls. Given that multituberculates diverged before rodents had evolved, would their overall similarity be homologous or convergent
Answers
Answer:
Convergent evolution
Explanation:
Convergent evolution can be described or explained as a process in evolution in biology. It usually occurs when two species from unrelated lines develop the same traits or features. This is believed to have happened due to the fact that they live in similar or related habitats, and have to develop solutions to the same kind of problems.
Therefore, in this case, the type of evolution between the two organisms mentioned is convergent.

Albino is a rare recessive genetic disease. Sally and her parents are normal but her sister is albino. It seems that Sally has chance to carry the albino allele. If she marries a normal person with no family history of albinos, what is the chance for Sally's first baby to be a carrier of the recessive allele?
Answers
Answer:
2/3 ×2/3× 1/4
Explanation:
Albino is a rare recessive genetic disorder which is characterized by low production of melanin or no melanin production. It is an inheritable disorder can be pass from generation to generation. Since the parent of Sally has no Albino and Sally sisters has, it means there is an history of Albino in the family that make her sister to have. She has 2/ 3 chance of having and the possibility that her first child will have is 1/4 meaning 25% because her hubby has no Albino history in their family.

TP53 is a recessive gene and is not located on the X chromosome, why would people who inherit just one mutant copy of a recessive tumor-suppressor gene be at higher risk of developing cancer than those without the recessive gene?
Answers
Answer:
Explanation:
Since it is a recessive gene, tumor suppressor genes required the inactivation of both alleles, this is usually accomplished by the mutation of one allele and a targeted homozygous deletion of the second allele. This leads to an effective inactivation of the suppressor genes with the mutations acting a a dominant negatives. This way, patients are put at a higher risk of developing cancer

Answers
Answer:
Receptor tyrosine kinases undergo autophosphorylation.
Explanation:
The receptor tyrosine kinases (RTKs) are proteins that undergo dimerization and autophosphorylation after binding with their corresponding ligands, thereby triggering downstream molecular signaling cascades. The RTKs bind with high specificity to ligands including growth factors, hormones and cytokines. In human cells, there are 58 types of RTKs proteins that function to regulate developmental pathways, and their dysfunctions have been associated with cancer progression.
