Question

what is the function of trna (transfer rna)?
a. to deliver amino acids to ribosomes
b. to carry genetic instructions
c. to build the ribosome structure
d. to proofread and repair errors in dna replication

Explanation:

tRNA (Transfer RNA) is involved in protein synthesis. During translation, it binds to specific amino acids in the cytoplasm and transports them to the ribosomes, where the amino acids are assembled into proteins.

• Option a: This is correct as tRNA's main role is to deliver amino acids to ribosomes for protein synthesis.
• Option b: mRNA (messenger RNA) carries genetic instructions, not tRNA.
• Option c: rRNA (ribosomal RNA) is involved in building the ribosome structure, not tRNA.
• Option d: Enzymes like DNA polymerase proofread and repair errors in DNA replication, not tRNA.

Answer:

A. To deliver amino acids to ribosomes
