Question

Which step happens first in translation?
O
A. A tRNA molecule attaches to a codon.
O
B. The amino acid pulls apart from tRNA.
O
c. The amino acids form peptide bonds.
O
D. The ribosome reaches the start codon.

Answer 1

Answer:

A. A tRNA molecule attaches to a codon.

Explanation:

The first step of translation is that a tRNA molecule attaches to a codon. These tRNAs (transfer RNAs) bring the amino acids to the ribosome - rRNA complex, where they connect to the codons and are arranged into a full protein.
