Question

In translation, an initiation complex consists of ______.

विकल्प

• an initiator tRNA

• a large ribosomal subunit

• a small ribosomal subunit

• the start codon of mRNA

Answer 1

In translation, an initiation complex consists of a large ribosomal subunit.

Explanation:

The “assembled” initiation complex means the intact ribosome ready to start elongation: after the small (40S/30S) subunit, mRNA (start codon) and initiator tRNA pair, the large (60S/50S) subunit joins to form the complete initiation complex (80S in eukaryotes, 70S in prokaryotes), so the large subunit is included.
