Detailed explanation-1: -ribosomal RNA (rRNA) – a type of RNA that assists in the protein-making process. rRNA is found in the cell’s ribosomes. ribosome – a molecular machine that coordinates protein assembly. A ribosome consists of two parts, a large and small subunit, which clamp around an mRNA molecule that needs to be translated.

Detailed explanation-2: -Ribosomal RNA (rRNA) rRNAs are found in the ribosomes and account for 80% of the total RNA present in the cell. Ribosomes are composed of a large subunit called the 50S and a small subunit called the 30S, each of which is made up of its own specific rRNA molecules.

Detailed explanation-3: -Messenger RNAs can be translated simultaneously by several ribosomes in both prokaryotic and eukaryotic cells. Once one ribosome has moved away from the initiation site, another can bind to the mRNA and begin synthesis of a new polypeptide chain.

Detailed explanation-4: -The RNA found in ribosomes, the molecules responsible for catalysing protein synthesis, is known as ribonucleic acid (rRNA).

Detailed explanation-5: -The rRNA (ribosomal RNA) makes up the ribosome. The ribosome builds the protein according to the instructions written in the mRNA with the amino acids ferried in by the tRNA.
