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).he lagging strand of DNA is that strand of the DNA double helix that is orientated in a 5' to 3' manner. Therefore, its complement must be synthesized in a 3'â5' manner. Because DNA polymerase III cannot synthesize in the 3'â5' direction, the lagging strand is synthesized in short segments known as Okazaki fragments.
