The presence of introns in genes can lower mutation rates and enable alternative splicing, allowing a single gene to produce multiple proteins with varying functions. This contributes to greater biological complexity and may enhance adaptability. Regulatory RNAs such as siRNA, which are encoded by introns, play a role in regulating gene expression.

What is a possible evolutionary advantage of having intronsexons in.pdf
- 1. What is a possible evolutionary advantage of having introns/exons in genes? Give an example of where this usage is observed or may have occurred. Solution Presence of large noncoding sequences such as introns interspersed with exons in the genome lowers the rate mutations from appearing. Introns enable alternative splicing, a mechanism which enables a single gene to encode multiple proteins that perform different functions under different conditions. Small genome but large information stored. Regulatory RNAs such as siRNA encoded by introns are known to regulate gene expression. Adds to biological complexity.
