Which of the following processes is the first event to take place in translation?
A
Base pairing of charged methionine-tRNA to AUG of the messenger RNA.
B
Binding of the larger ribosomal subunit to smaller ribosomal subunits.
C
The ribosome reaches a stop codon.
D
The small subunit of the ribosome recognizes and attaches to the mRNA.
Verified step by step guidance1
Understand that translation is the process by which ribosomes synthesize proteins using mRNA as a template.
Recognize that translation involves several key steps: initiation, elongation, and termination.
In the initiation phase, the small ribosomal subunit plays a crucial role by first binding to the mRNA strand.
The small ribosomal subunit scans the mRNA to find the start codon (AUG), which is the signal for the beginning of protein synthesis.
Once the start codon is located, the charged methionine-tRNA pairs with the AUG codon, setting the stage for the larger ribosomal subunit to join and form a complete ribosome, ready for elongation.
