WebbThe summary of the various steps in the mechanism of protein synthesis is shown in (Fig. 13). Step 1 — Transcription: One strand of DNA molecule functions as a template for the formation of mRNA. This mRNA contains the message for the protein to be synthesised. Webb2) Peptide bond formation: a peptide bond is formed between the incoming amino acid (carried by a tRNA in the A site) and methionine (a tRNA charged with methionine attached to the P site during initiation). This …

WebbAs with mRNA synthesis, protein synthesis can be divided into three phases: initiation, elongation, and termination. The process of translation is similar in prokaryotes and eukaryotes. Here we’ll explore how translation occurs in E. coli, a representative prokaryote, and specify any differences between prokaryotic and eukaryotic translation. WebbThere are two main steps in splicing: In the first step, the pre-mRNA is cut at the 5' splice site (the junction of the 5' exon and the intron).
