What is rRNA?

Ribosomes are complexes of rRNA molecules and proteins. Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

rRNA = ribosomal RNA

Ribosomes are composed of two components - rRNA and ribosomal proteins. Ribosomes are important because they are enzymes which catalyse the process of protein synthesis and translation.

r RNA is a Ribosomal ribonucleic acid, it is non-coding RNA essential to all cells. responsible for protein synthesis.

here is a brief description of RNA the key differences between DNA and RNA along with the different types of RNA and their function. Remember also that DNA has a deoxyribose sugar in its nucleotide where as RNA only has a ribose sugar.
