    • 2.1: Overview of Transcription
      All cells make three main kinds of RNA: ribosomal RNA (rRNA), transfer RNA (tRNA) and messenger RNA (mRNA). rRNA is a structural as well as enzymatic component of ribosomes, the protein-synthesizing machine in the cell. Quantitatively, rRNAs are by far the most abundant RNAs in the cell and mRNAs, the least. Three rRNAs and about 50 ribosomal proteins make up the two subunits of a bacterial ribosome, as illustrated below.
