Solution
The correct option is B mRNA Amino acid sequence in protein synthesis is decided by the sequence of mRNA. mRNA is attached with ribosomes. Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
