WebThere are three types of RNA polymerases that all transcribe different genes. RNA polymerase I transcribes genes encoding ribosomal RNA (rRNA) which is a main component of a cell’s ribosome structure. Ribosomes are the site of protein syntehsis where mRNA is translated into a protein. WebThe same RNA polymerase transcribes all of the genes in prokaryotes. In E. coli, RNA polymerase is a pentamer composed of five polypeptide units, two of which are the same. The polymerase core enzyme is made up of four subunits designated as α, α, β, and β′ with another additional subunit to form the holoenzyme. dr sherif raouf genesiscare
