Which of the following cell organelles is made up of ribosomal RNA and protein?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Ribosome.
The cell organelle made up of ribosomal RNA (rRNA) and protein is the ribosome. Ribosomes are essential for protein synthesis in cells, where they translate messenger RNA (mRNA) sequences into polypeptide chains. They consist of two subunits: a small subunit and a large subunit, both of which are composed of rRNA and proteins. These subunits come together to facilitate the translation process, playing a critical role in the cell's protein-making machinery.
