You are examining the DNA sequences that code for the enzyme phosphofructokinase in skinks and Komodo dragons. You notice that t

he coding sequence that actually directs the sequence of amino acids in the enzyme is very similar in the two organisms but that the surrounding sequences vary quite a bit. What is the most likely explanation for this?
A. Coding sequences are repaired more efficiently.
B. Coding sequences are replicated more efficiently.
C. Coding sequences are packaged more tightly in th e chromosomes to protect them from DNA damage.
D. Mutations in coding sequences are more likely to e deleterious to the organism than mutations in noncoding sequences.
E. Recombination between skink and Komodo dragon DNA occurred recently

Answer:

The correct answer is D.

Explanation:

Mutations in coding sequences are more likely to be deleterious to the organism than mutations in non-coding sequences.

Mutations in coding sequence is more harmful because they end up mutating the protein coding region of the DNA , which alters the function of proteins.

These mutations may cause some harmful genetic disorder or end up causing cancer.  That is why mutations  in coding sequences are more harmful to the organism than mutations in non-coding sequences.
