Question

which molecule brings amino acids to the ribosomes to be assembled into proteins?
○ trna
○ mrna
○ peptide
○ codon

Explanation:

In protein synthesis, tRNA (transfer RNA) has the function of bringing specific amino acids to the ribosomes. mRNA (messenger RNA) carries the genetic code from DNA to the ribosome. A peptide is a short chain of amino acids (part of the protein being assembled, not the carrier). A codon is a sequence of three nucleotides on mRNA that codes for an amino acid, not a molecule that brings amino acids. So tRNA is the molecule that brings amino acids to ribosomes for protein assembly.

Answer:

A. tRNA
