Question

You are examing the DNA sequences that code for the enzymephosphofructokinase in skunks and komodo dragons. You notice thatthe coding sequence (exon) that actually directs the sequence ofamino acids in the enzyme is very similar in the two organisms butthat the surrounding sequences(introns) vary quite a bit. what isthe mostly like explanation for this? A. Mutations in coding sequences are more likely to bedeleterious to the organism mutations in noncoding sequences. B. Coding sequence are repaired more efficiently C. Coding sequences are packaged more tightly in thechromosomes to protect them from DNA damage D. Coding sequences are replicated more accurately E. DNA repair enzymes preferentially repair the newlyreplicated strand to match the original strand You are examing the DNA sequences that code for the enzymephosphofructokinase in skunks and komodo dragons.
