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 antisense strand of DNA is read by RNA polymerase from the 3' end to the 5' end during transcription (3' â 5'). The complementary RNA is created in the opposite direction, in the 5' â 3' direction, matching the sequence of the sense strand with the exception of switching uracil for thymine.ranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerase.
