Both types of selection show that "this non-coding DNA actually has functional importance to the organism," said Andolfatto. "We've known for a while that it was possible you'd see ...

Introns are non-coding sections of an RNA transcript, or the DNA encoding it, which are spliced out, or removed, before the RNA molecule is translated into a protein.

This discovery laid the foundation for understanding the structure and function ... of DNA to transcription factors and influence gene expression. In addition to protein-coding genes, the genome also ...

Genetic variation happens when one or more building blocks in DNA are changed ... newly identifying loss-of-function variants in both coding and non-coding regions (parts of the gene that don ...
