Non-coding regions are essential for the proper functioning of the genome. They contain sequences that regulate the transcription, translation, and stability of mRNA. Elements like promoters and enhancers are key in controlling when and where genes are expressed. Introns can influence gene expression through various mechanisms, including alternative splicing. Moreover, non-coding RNAs (ncRNAs) such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) also originate from these regions and are involved in gene regulation.
