When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference
REY [17]

Answer:

The best answer to the question: What is the most likely explanation for this observation, would be, B: RNA processing removes the different segments from the mRNA molecules of each person prior to translation.

Explanation:

In order for cells to work, they depend on one of the four major macromolecules; proteins. These proteins are the messengers that carry out genetic commands from the DNA and they will ensure that all processes, including transcription and translation of new proteins, are carried out correctly. In order to produce proteins, the first step is for the DNA to be transcribed into mRNA, a nucleic acid that carries out the information on the DNA for protein generation. Once transcription stops, mRNA undergoes a series of clipping and reorganizing steps that will ensure that when it is decoded for protein formation, the process will be successful. These control steps are all part of the RNA processing mechanism that enures mRNA will successfully be translated into working proteins.

The reason why from genes of different people, a very similiar protein chain may result, is also explained from the fact that codons (a grouping of three nucleotides present in mRNA), when read by ribosomes, and coupled by tRNA, can pair these codons with similar amino acids. Thus, one codon, or similar codons, may code for a singular amino acid. However, mechanisms in the cells prevent these kinds of anomalies, by repairing the mRNA sequence before it is translated into protein.

Select all of the following statements that are true concerning virus structure:
elena-s [515]

All the statement above are very true of what virus structure constitute.

This goes to say that viruses:

  • use DNA as their genetic material.
  • have a phospholipid bilayer envelope.
  • lack organelles, ribosomes, and a plasma membrane.
  • have a capsid.
  • require a host for replication.

<h3>What are viruses?</h3>

Viruses are seen and considered as the border line between living and non living things.

  • Viruses are living when they are inside another living organism. They are the smallest known microorganisms.
  • However, they are non-living when they are outside the system of a living thing

What are the functions of pharynx
bekas [8.4K]
There are basically 3 types of pharynx- nasopharynx, oropharynx and laryngopharynx.
The function of the pharynx are:-
1. To transport the food from mouth to esophagus. 
2. To warm, moisten and filter the air, before it moves to the trachea, and then to the bronchi, the bronchioles, the alveoli and at last to the lungs.
    Therefore, pharynx(or throat) is a part of both- digestive and respiratory systems.
3. It is also important for vocalization.

In E. coli protein synthesis, the initiation complex contains
Ksenya-84 [330]

Answer:

The correct answer will be option-C.

Explanation:

The process of translation in prokaryotes is complex process and proceeds in three steps: initiation, elongation and termination.

1. Ribosomal subunits: 50S (5S and 23S subunit) and 30S (16S and proteins).

2. Initiation factors: IF1, IF-2 and IF-3 which help in the formation of assembly.

3 GTP: guanosine triphosphate as a source of energy.

4. Charged tRNA: with N-formylmethionine is the first amino acid.

5. mRNA: the RNA to be translated.

Since the option contains both 50S and 16S components of ribosome thus, Option-C is the correct answer.
