Which statements are true about variations in the genetic code?
Murrr4er [49]

Answer:

<u>C) They may provide selective advantages. </u>

<u>D) Slight differences in the genetic code may have significant results.</u>

Explanation:

The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.  

DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.

Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment.  Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.
