RRNA

Ribosomal ribonucleic acid (rRNA) is the polynucleotide that make up 60% of the structure of ribosomes, which are used for translation. It is the most abundant type of RNA in a cell.

In the cell rRNA, decodes mRNA and translates it into amino acids. The rRNA interacts with tRNA (transfer RNA) which brings with it amino acids which correspond to the 3 base code on the mRNA sequence.
