Introns represent a genome scrap yard that provides DNA segments for genome evolution and a variety of small RNA molecules.

Question

Quizplus · Accepted Answer

Introns are non-coding regions of DNA that are transcribed into RNA but are usually spliced out before translation. However, recent research has shown that introns have a variety of functions including providing genetic material for genome evolution through alternative splicing, as well as producing small RNA molecules that play important regulatory roles in gene expression. Therefore, introns should not be considered a "scrap yard" but rather an essential part of the genome.
