Question

Which step happens first in translation?

A. The amino acids form peptide bonds.
• B. A tRNA molecule attaches to a codon.
• C. The ribosome reaches the start codon.
• D. The amino acid pulls apart from tRNA.

Answer 1

A. A tRNA molecule attaches to a codon.

Step-by-step 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.
