Which Type of DNA Sequence Exhibits the Highest Evolutionary Rates

Question

Which type of DNA sequence exhibits the highest evolutionary rates?
A) Nucleotides in the second position of a codon
B) Nucleotides in the first position of a codon
C) Pseudogenes
D) Introns
E) Rates among DNA sequences do not vary

Accepted Answer

Pseudogenes exhibit the highest evolutionary rates because they are non-functional copies of genes and are not subject to selective pressure, allowing mutations to accumulate more freely.
