RNA polymerase an enzyme responsible for copying DNA sequence

A record factor and its related record middle person complex should be joined to a DNA restricting site called an advertiser locale before RNAP can start the DNA loosening up at that position. RNAP not just starts RNA record, it additionally controls the nucleotides into position, encourages connection and stretching, has inherent editing and substitution capacities, and end acknowledgment ability. In eukaryotes, RNAP can fabricate chains as long as 2.4 million nucleotides.
