In the coding region, natural selection tends to eliminate all of the mutations because of the high importance these regions have. The coding region contains genes that synthesize proteins and the changes in the DNA sequence can have devastating effects on the cell. Therefore, there are very few differences in the sequences of coding regions that can help us trace the lineage.
On the other hand, in the non-coding regions, the mutations often accumulate because they have little effect on the cell and the adaptive value of the organism. This enables us to trace up the lineage by comparing the sequences and seeing the differences in the sequences.
All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity. Homeostasis is necessary for normal life processes that take place inside cells.
Answer:
C) translation rate
Explanation:
The process of gene expression involves DNA transcription into mRNA and translation of mRNA into protein.
During transcription, genetic message in DNA is encoded into mRNA. The encoded messages are then translated into their respective amino acids during the process of translation.
<em>Hence, if a virus uses its genome as mRNA, the next stage will be to translate the messages in the mRNA into amino acids. Translation rate is expected to be measurable.</em>
The correct option is C.
