Question

what is the role of rrna in translation?
a. it reads mrna and helps form peptide bonds between amino acids.
b. it leaves the nucleus and carries the genetic code to a ribosome.
c. it holds an anticodon on one end and an amino acid on the other end.
d. it combines with the golgi apparatus to form ribosomes.

Explanation:

rRNA (ribosomal RNA) is a component of ribosomes. Ribosomes are the sites of translation. During translation, ribosomes (containing rRNA) read the mRNA (messenger RNA) sequence and facilitate the formation of peptide bonds between amino acids.

• Option B: Leaving the nucleus and carrying the genetic code to a ribosome is the role of mRNA, not rRNA.
• Option C: Holding an anticodon on one end and an amino acid on the other end is the role of tRNA (transfer RNA), not rRNA.
• Option D: rRNA combines with proteins (not the Golgi apparatus) to form ribosomes.

Answer:

A. It reads mRNA and helps form peptide bonds between amino acids.
