WebFigure 9.21 Translation begins when a tRNA anticodon recognizes a codon on the mRNA. The large ribosomal subunit joins the small subunit, and a second tRNA is recruited. As the mRNA moves relative to the ribosome, the polypeptide chain is formed. Entry of a release factor into the A site terminates translation and the components dissociate. WebInfo. Promoters are DNA sequences located in the 5' region adjacent to the transcriptional start site. RNA polymerase and accessory proteins (transcription factors) bind to the promoter to initiate production of an mRNA transcript. Interactions of proteins at the promoter regulate gene actvity by activating or repressing transcription.

Web23 apr. 2024 · Translation is the final step in the path representing the central dogma of molecular biology: DNA to RNA to protein. Translation involves the ribosome, mRNA, tRNA and amino acids.
