Introduction to Exons and Introns
Definition of Exons and Introns
Exons and introns are fundamental components of genes , playing distinct roles in the process of gene expression. Exons are the coding sequences that are retained in the final messenger RNA (mRNA) after transcription. They provide the necessary information for synthesizing proteins.
