What is Protein-coding region ?

Protein-coding regions of genes, also known as exons, represent the functional segments of DNA that carry the instructions for protein synthesis.

• Genes: These are discrete units of hereditary information composed of DNA.

• Exons: Within a gene, exons are the segments that contain the actual genetic code, translated into the amino acid sequence of a protein.

• Introns: These are non-coding regions within a gene that are interspersed between exons. Introns are transcribed into RNA but are later removed through a process called splicing, leaving only the exons to be translated into protein.

Therefore, exons are the critical elements within a gene that ultimately determine the structure and function of the proteins that drive cellular processes.

Ok ! But you might think what's the difference between Exon and Exome then !
