Question

what type of rna is in ribosomes?
mirna
rrna
-trna

Explanation:

To determine the type of RNA in ribosomes, we recall the functions of different RNA types. Ribosomal RNA (rRNA) is a major component of ribosomes, forming the structural and catalytic core of the ribosome. miRNA (microRNA) is involved in gene regulation, not ribosome structure. tRNA (transfer RNA) brings amino acids to the ribosome but is not a component of the ribosome itself. So the RNA in ribosomes is rRNA.

Answer:

B. rRNA (assuming the option with rRNA is the correct one; based on the visible option "rRNA" in the image, the correct answer is the option labeled "rRNA")
