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.
RNA polymerase lacking sigma subunit is called the core RNA polymerase. RNA is synthesized in the 5' to 3' direction (the same direction as DNA is synthesized). The synthesis of RNA does not require a primer, but does require a DNA template strand.he portion of DNA copied is referred to as the template. Like DNA synthesis, transcription proceeds in the 5' to 3' direction. RNA polymerases differ from DNA polymerases in a couple of important respects. First, RNA polymerases do not require a primer.
