what does rRNA do
RNA polymerase is the protein that makes the copy of DNA. Ribosomal RNA (rRNA) is part of the ribosome, or protein builders of the cell. Ribosomes are responsible for translation or the process our cells use to make proteins.rRNA are responsible for reading the order of amino acids and linking amino acids together. They do this through a highly complex sequence.o begin, ribonucleic acids (RNA) are a group of large molecules that have many different roles. They are especially important in the coding, decoding, regulation, and expression of our genes. As the name implies, ribosomal RNA (rRNA) is part of the ribosome. A ribosome is the protein builder of the cell.
