The following points highlight the four main processes to produce mRNA from RNA. The processes are: 1. Splicing 2. Capping 3. Polyadenylation 4. RNA Editing. Process # 1. Splicing: This process takes place in the nucleus and involves the removal of noncoding intron sequences from pre-mRNAs to produce mature mRNAs in which the coding sequences, […]

The following points highlight the three main stages for translation of RNA and protein synthesis. The stages are: 1. Initiation of Polypeptide 2. Elongation of Polypeptide: 3. Termination of Polypeptide. Translation of RNA: Stage # 1. Initiation of Polypeptide: Ribosomes exist as separate large and small subunits. The first step in translation involves the binding […]

In this article we will discuss about the Transcriptional and Post-Transcriptional Regulation in Prokaryotes. Transcriptional Regulation of Gene Expression in Prokaryotes: Gene transcription is regulated in bacteria through a complex of genes termed operon. These are transcriptional units in which several genes, with related functions, are regulated together. Other genes also occur in operons which […]
