Question

what type of rna is joined with proteins to form ribosomes?
trna
rrna
mrna

Explanation:

Ribosomes are composed of ribosomal RNA (rRNA) and proteins. Messenger RNA (mRNA) carries genetic information, and transfer RNA (tRNA) brings amino acids. So rRNA combines with proteins to form ribosomes.

Answer:

The correct option (assuming the middle option is rRNA, e.g., if options are tRNA, rRNA, mRNA: B. rRNA)
