Question

2.1.2 quiz: protein synthesis
question 7 of 10
what is the role of trna during translation?
a. it acts as the translator between the mrna sequence and the growing polypeptide.
b. it contributes to the structure of the ribosome and ribosomal functions.
c. it carries the genetic code for a protein out of the nucleus to the site of protein synthesis.
d. it binds nucleotides together to form rna sequences from dna.

Explanation:

tRNA has an anticodon that pairs with mRNA codon and carries specific amino acids to the ribosome for polypeptide synthesis, thus acting as a translator. Option B is for rRNA (ribosomal RNA). Option C is for mRNA (messenger RNA). Option D is not a function of tRNA.

Answer:

A. It acts as the translator between the mRNA sequence and the growing polypeptide.
