Answer:
the amount of A was equal to the amount of T
amount of C and the amount of G
Answer:
The answers are the second and fourth ones.
Explanation:
I did the assignment.
Codons that code for the same amino acid are termed synonyms, Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Answer:
Codons are
3
base "words" that code for specific amino acids. They are
nonoverlapping
and never
have gaps between
the words.
