Which of the following components is directly responsible for bringing amino acids to the ribosome during translation?

• A. tRNA
• B. DNA polymerase
• C. mRNA
• D. rRNA

Answer: (A)

Verified step by step guidance

1. Understand the process of translation, which is the synthesis of proteins from mRNA templates in the ribosome.
2. Recall that during translation, amino acids must be delivered to the ribosome to be assembled into a polypeptide chain.
3. Identify the molecule responsible for carrying specific amino acids to the ribosome by matching its anticodon with the codon on the mRNA.
4. Recognize that transfer RNA (tRNA) is the component that physically brings amino acids to the ribosome during translation.
5. Differentiate tRNA from other molecules: DNA polymerase is involved in DNA replication, mRNA carries the genetic code from DNA, and rRNA is a structural and catalytic component of the ribosome.
