Question

Needed for _________ in prokaryotes. 1) mRNA 2) 30S and 50S ribosomal subunits 3) a set of proteins known as initiation factors 4) GTP 5) F-Met-tRNA.

A. Transcription
B. Replication
C. Translation
D. DNA repair

Answer 1

The initiation of translation in prokaryotes requires mRNA, 30S and 50S ribosomal subunits, initiation factors, GTP, and F-Met-tRNA.

Step-by-step explanation:

Translation is the process of protein synthesis in which the information carried by mRNA is used to produce a protein. In prokaryotes, such as E. coli, the initiation of translation requires the following components:

1. mRNA: The template molecule that carries the genetic information for protein synthesis.
2. 30S and 50S ribosomal subunits: The subunits that make up the ribosome, a complex responsible for protein synthesis.
3. Initiation factors: A set of proteins that help in the assembly of the initiation complex and ensure the correct start of translation.
4. GTP: Guanosine triphosphate, which acts as an energy source during translation.
5. F-Met-tRNA: A special initiator tRNA that carries the amino acid methionine and interacts with the start codon AUG.
