Pregunta:

Explain why the mutation rate is different between exons and introns under negative selection pressure?

Autor: Shay 1vcc



Respuesta:

Mutations occur at the same rate in both exons and introns, but exon mutations are eliminated more effectively by selection. However, because of the low level of functional constraints, introns may more freely accumu­late point substitutions and other changes.
