Introns are significant to biological evolution because
A)their presence allows exons to be shuffled.
B)they protect the mRNA from degeneration.
C)they are translated into essential amino acids.
D)they maintain the genetic code by preventing incorrect DNA base pairings.
E)they correct enzymatic alterations of DNA bases.

Question

Quizplus · Accepted Answer

Introns are non-coding regions of DNA that interrupt coding regions called exons, and their presence allows for exon shuffling during meiosis. This genetic recombination generates new combinations of exons, creating new genes and promoting genetic diversity. This process is essential for biological evolution, as it drives the development of novel traits and adaptations.
