Transcription is the process of mRNA synthesis. It occurs in the nucleus before translation. During transcription, RNA bases pair DNA bases, replacing Thymine with Uracyl. You will find the example in the explanation.
Note: The DNA sequence is missing, so I will provide a new sequence and explain the procedure. I suggest you perform the same steps with your molecule fragment and reach the correct mRNA.
Protein synthesisProteins synthesis is done in two stages: transcription and translation. The whole process begins in the nucleus and finishes in the cytoplasm.Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA. Once the new molecule is completed, it is sent to its final destiny.Transcription:The first step before protein arrangement is to synthesize messenger RNA, mRNA. This is the transcription process and occurs in the nucleus. When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand. The coding strand goes in direction 5' to 3', while the complementary strand -template strand- grows in direction 3' to 5'. This last segment is the one that is going to be complemented by the mRNA. It is the template strand. A template DNI strand is read in direction 3'→ 5' to build the mRNA molecule that grows in direction 5'→ 3'.During transcription bases forms pairs. RNA replaces Thymine with Uracyl, so pairs are as follows,DNA mRNA
Adenine pairs Uracyl, Thymine pairs Adenine, Guanine pair Cytosine, Cytosine pair Guanine.Translation:
Translation occurs in the cytoplasm. During translation, rRNA reads mRNA in 5' to 3' direction, and tRNA adds the correct amino acid to the growing chain. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.ExampleWe will consider for this example the following DNA template strand.
DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
Transcription
template DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
The new mRNA strand is
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
Once the mRNA synthesis is over, the molecule leaves the nucleus and proceeds with translation in the cytoplasm.

Answer:
the advantage is free more space to plant crops and farm animals and build houses
the disadvantage is destroying the animal environment and may cause climate change and killing an endangered species by destroying there houses or by accident
Answer:
As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere and more space.

Order of DNA Replication
The order of Replication include the following:
DNA helicase unwinds DNA.Replication fork is formed.DNA polymerase attaches to primer.DNA polymerase adds nucleotides (5' to 3').Okazaki fragments bound by ligase.DNA replication involves the production of two copies of DNA from one
DNA. The enzyme known as helicase helps to unwind DNA into single
strands after which a replication fork is formed from the two single strands.
DNA polymerase attaches to the primer and the DNA polymerase adds
nucleotides to the leading strand of DNA in the 5' to 3' direction. Okazaki
fragments, which are small fragments of DNA are bound together by ligase
enzyme to complete the process.

Scientific names are understood by all scientists because the names are written in
Answer:
A. binomial system
B. According to taxon
Explanation:
A. The binomial system of nomenclature brings order to a chaotic world of common names. No two kinds of animals have the same binomial name, and every animal has only one correct name, as required by the International Code of Zoological Nomenclature, thereby avoiding the confusion that common names cause.
B. Any grouping of animals that shares a particular set of characteristics forms an assemblage called a taxon. For example, a housefly (Musca domestica), although obviously unique, shares certain characteristics with other flies (the most important of these being a single pair of wings). Based on these similarities, all true flies form a logical, more inclusive taxon. Further, all true flies share certain characteristics with bees, butter-flies, and beetles. Thus, these animals form an even more inclusive taxon. They are all insects.

What are Eukaryotic organisms?Eukaryotic organisms may be defined as those organisms whose cells have a well-defined nucleus and the existence of membrane-bound cell organelles. They are single-celled or multicellular in nature. They belong to the group of organisms Eukaryota or Eukarya.
There is a large range of eukaryotic organisms in nature. Examples of eukaryotic organisms are all animals, plants, fungi, protists, and most algae. While bacteria are classified into the category of prokaryotic organisms.
Viruses are neither eukaryotic nor prokaryotic in nature. This is because they are non-cellular and can not able to multiply or reproduce outside the living host.
Therefore, eukaryotic organisms are fungi, plants, and animals. Thus, the correct options are B, C, and E.

Which layer of the ocean is the least dense?
Q4 options:
they are all the same
closest to the ocean floor
closest to the surface
middle layer
Answer:
Q1: C. salinity Q2: density Q3: B. densest, least dense Q4: C. closest to the surface
Explanation:
Q1: The term "salinity" refers to the concentrations of salts in water or soils. Q2: when the amount of salt in the water increase which usually gathers mostly at the shallow top of the ocean which is where the warm shallow water gathers, when the warm water has enough salt in it, it sinks to a deeper location causing its density to heighten and that's also what makes it cold. Q3: When layers form in the ocean, the water containing the most dissolved salt tends to form the bottom layer. The water having the least amount of salt is usually on top, because it is the least dense. As more solids are dissolved in water, the water becomes more dense. Q4: Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. I really need brainliest please do so.

14. In the summary equation below, which process produced the lactic acid? enzymes glucose 2 lactic acid + 2 ATP
Answer:
Fermentation (anaerobic respiration)
Explanation:
Fermentation is also called anaerobic respiration, and it involves the breakdown of glucose in the absence of oxygen. Fermentation, which is carried out by some microbes, is named based on the type of product. There is alcoholic fermentation and lactic acid fermentation.
Lactic acid fermentation is the process whereby glucose is broken down to produce lactic acid. According to the summarized equation given in the question, lactic acid is formed by the enzymatic breakdown of glucose.
Enzymes + glucose → 2 lactic acid + 2ATP
Two ATP molecules and 2 lactic acid molecules are given as products in the reaction.

What’s 2 similarities and 2 differences between the Earths layers and the atmospheric layers?
Answer:
Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. The atmosphere thins out in each higher layer until the gases dissipate in space.
Explanation:
The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.
