What is rRNA?

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.

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

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.

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.
