How is translation initiated in cell biology?

The small ribosomal subunit binds to the mRNA The tRNA bearing methionine binds to the start codon , The large ribosomal subunit binds to the small one. The start codon signals the start of translation


What amino acid is encoded by the initiation codon AUG?

The amino acid that is encoded by the initiation codon AUG is methionine. It is the only amino acid which is specified by just one codon.


What is the difference between the Kozak sequence and the Shine-Dalgarno sequence in terms of their roles in translation initiation?

The Kozak sequence is found in eukaryotic mRNA and helps the ribosome to identify the start codon for translation initiation. The Shine-Dalgarno sequence is found in prokaryotic mRNA and helps the ribosome to bind to the mRNA and start translation. Both sequences play important roles in translation initiation, but they are specific to different types of organisms.

How is the initiation of translation regulated within the cell?

The initiation of translation in a cell is regulated by a complex process involving several key factors. One important regulator is the binding of the ribosome to the mRNA molecule, which is facilitated by initiation factors. Another crucial step is the recognition of the start codon on the mRNA by the initiator tRNA. Additionally, regulatory proteins and signaling pathways can influence the initiation of translation by controlling the availability of initiation factors and ribosomes. Overall, the regulation of translation initiation ensures that protein synthesis is carefully controlled and coordinated within the cell.

What is the step of translation in which an mRNA a small ribosomal subunit and the initiator tRNA are aligned together is?

The step of translation in which an mRNA, a small ribosomal subunit, and the initiator tRNA are aligned together is called initiation. This process occurs with the formation of the initiation complex, where the mRNA binds to the small ribosomal subunit and the initiator tRNA carrying methionine binds to the start codon on the mRNA.


What are the three stages called for Initiation elongation and termination?

The three stages in protein synthesis are initiation, elongation, and termination. In initiation, the ribosome assembles on the mRNA and finds the start codon. During elongation, amino acids are added to the growing polypeptide chain. Termination occurs when a stop codon is reached, signaling the end of protein synthesis.
