3.5.5: Discuss the relationship between one gene and one polypeptide.

3.5.5: Discuss the relationship between one gene and one polypeptide. One gene may code for multiple polypeptides due to alternative splicing (Post transcriptional modification). mRNA from one gene. Introns are transcribed but not translated Exons are transcribed and translated.
