A significant proportion of functional DNA sequences are __________ and thus are _______ parts of the genome.

Question

Quizplus · Accepted Answer

Functional DNA sequences are those that serve a purpose, such as encoding proteins or regulating gene expression. While some functional sequences may be highly conserved among different species, meaning they have remained relatively unchanged throughout evolution, others may be constantly evolving and not highly conserved. This is because the function of these sequences may depend on their specific nucleotide sequence, rather than their conservation. Therefore, choice B, which states that functional sequences are constantly evolving and not highly conserved, is the best choice.
