Which of the following types of RNA carries amino acids to the ribosome during protein synthesis?
A.
Messenger RNA
B.
Ribosomal RNA
C.
Transfer RNA
D.
Small nuclear RNA
The correct answer is:
C. Transfer RNA
Explanation: Transfer RNA (tRNA) is responsible for carrying amino acids to the ribosome during protein synthesis. Each tRNA molecule has an anticodon that pairs with a corresponding codon on the messenger RNA (mRNA) strand, ensuring that the correct amino acid is added to the growing polypeptide chain.
- A. Messenger RNA (mRNA) carries the genetic code from DNA to the ribosome but does not carry amino acids.
- B. Ribosomal RNA (rRNA) is a component of ribosomes and plays a role in protein synthesis but does not carry amino acids.
- D. Small nuclear RNA (snRNA) is involved in splicing pre-mRNA but does not carry amino acids.
