DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand.
The enzyme RNAp transcribes a RNA strand from the DNA helix. RNAp initiates transcription in the presence of promoter specific Ï factors, elongates the nascent RNA and terminates transcription. RNA polymerase synthesizes nucleic acids in the 5â to 3â direction while reading a DNA template in the 3â to 5â direction.The Ï is released soon after the transcription of 10bp (base pairs) of the growing RNA chain therefore it is restricted to promoter recognition and transcription initiation.NAp initiates transcription in the presence of promoter specific Ï factors, elongates the nascent RNA and terminates transcription. RNA polymerase synthesizes nucleic acids in the 5â to 3â direction while reading a DNA template in the 3â to 5â direction.
