#Unit 2. Cellular Organization

Introns evolve or accumulate mutations/changes much more rapidly than exons

#Unit 2. Cellular Organization

Intron do not face selective pressure to produce a polypeptide with a useful sequence hence highly variable.

#Unit 2. Cellular Organization

Exon sequences are conserved by the negative selection of individuals in which the sequences have changed

#Unit 2. Cellular Organization

Most intron mutations are expected to be selectively neutral except branch site, splicing junctions, and sequences influencing splicing

#Unit 2. Cellular Organization

A mutation that confers a more advantageous phenotype to an organism, relative to Individuals in the same population without the mutation, is positive selection of that organism.
