Protein biosynthesis is the process by which biological cells generate new proteins. Here are the reasons for some protein synthesis related molecular events. 1.Transcription is especially important in terms of gene expression. – Because transcription is the point where most of the regulation of gene expression occurs. 2. Dissociation of sub-unit of ribosome is essential
