Which of the following molecules transfers amino acids present in the cytoplasm to the ribosomes during protein synthesis?
A
tRNA (transfer RNA)
B
rRNA (ribosomal RNA)
C
DNA (deoxyribonucleic acid)
D
mRNA (messenger RNA)
Verified step by step guidance1
Understand the role of each type of RNA in protein synthesis: mRNA, tRNA, and rRNA.
mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.
rRNA (ribosomal RNA) is a component of ribosomes and plays a role in catalyzing the formation of peptide bonds between amino acids.
tRNA (transfer RNA) is responsible for transporting amino acids from the cytoplasm to the ribosome, where they are added to the growing polypeptide chain.
Identify that tRNA is the molecule that transfers amino acids to the ribosome during protein synthesis, making it the correct answer.
