Exons in AP Biology

Definition

Exons are the sections of DNA that are transcribed into mRNA and then translated into proteins. They contain the actual genetic information coding for protein synthesis.

Related terms

Introns:

These are non-coding regions of DNA within a gene; they are transcribed into RNA but not translated into protein.

Coding Sequence: This is a sequence of codons in DNA or RNA, which results in a particular amino acid sequence when translated.

Gene Expression:

This is the process by which information from a gene is used to synthesize a functional gene product (like proteins).
