Which of the following types of RNA molecules is responsible for guiding the assembly of amino acids during protein synthesis?

A Messenger RNA (mRNA)
B Transfer RNA (tRNA) ✓
C Ribosomal RNA (rRNA)
D Small nuclear RNA (snRNA)

Explanation

Transfer RNA (tRNA) molecules play a crucial role in guiding the assembly of amino acids during protein synthesis by recognizing specific codons on the mRNA and bringing the corresponding amino acids to the ribosome.
