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 polymerase starts replication at the 3'-end of the primer, and copies the opposite strand. In most cases of natural DNA replication, the primer for DNA synthesis and replication is a short strand of RNA (which can be made de novo).n eukaryotic primer removal, DNA polymerase Î´ extends the Okazaki fragment in 5' to 3' direction, and when it encounters the RNA primer from the previous Okazaki fragment, it displaces the 5â² end of the primer into a single-stranded RNA flap, which is removed by nuclease cleavage.
