Why is RNA necessary for protein synthesis?

Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.

Explanation:

The blueprints for constructing proteins are given by messenger RNA to the ribosome. Proteins are made up of amino acids, which are the building blocks. Another kind of RNA, transfer RNA, transports each amino acid in a protein to the ribosome (tRNA).

not too sure but maybe in the hot springs.
