Answer #1

Answer: 3, 5, and 7

Option 1 – No

Explanation: Initiator factor, tRNA-methionine along with the small ribosomal subunit bind to the 5' cap of the mRNA for scanning not at 3-Poly(A) tail.

Option 2 – No

Explanation: Start codon recognition triggers the release of initiation factor (eIF-1) and conversion of eIF-2 to its GDP bound state which, thereby arrests the scanning process.

Option 3 – Yes

Explanation: The ribosome's large subunit (60S) joins the small subunit (40S) bound with the initiation codon (AUG) to form an 80S ribosome.

Option 4 – No

Explanation: C-terminus is present in proteins or peptides not in mRNA,

Option 5 – Yes

Explanation: Initiator factor, tRNA-met along with the small ribosomal subunit bind to the 5' cap of the mRNA and scan to find the AUG start codon.

Option 6 – No

Explanation: DNA polymerase is an enzyme for replication not translation.

Option 7 – Yes

Explanation: The ribosome's large subunit (60S) binds to the small subunit to form an active ribosome that is competent for the elongation step.
