B) transfer RNAs.
C) ribosomal RNAs.
D) messenger RNAs.
E) ribosomes.

Question

Quizplus · Accepted Answer

Transfer RNAs (tRNAs) have specific sequences that allow them to bind to a particular amino acid on one end and a specific codon on the other end, making them the adapters that facilitate translation. Aminoacyl-tRNA synthetases are enzymes that attach amino acids to the tRNA, while ribosomal RNAs (rRNAs) are part of the ribosome complex that helps catalyze the formation of peptide bonds between amino acids. Messenger RNAs (mRNAs) carry the genetic information from DNA to the ribosome, and ribosomes are protein-RNA complexes that facilitate translation. However, tRNAs are specifically responsible for the translation of the genetic code from nucleic acids to amino acids.
