The 'Behaviour' of Replication

DNA replication is a necessary process during the function if cellular division. As each cell divides, it requires a clone copy of its 'instructor' DNA. Since the DNA is itself responsible for creating the very processes which guide all cellular behaviours (in the sense that it directs creation of which proteins exist within the cell, hence guiding the cells behavioural functions), it is a necessary and required component of any cells makeup. DNA replication is very similar to the act of transcription, albeit in this case, DNA is the target of creation rather than RNA.


As you can imagine, the process of replication is relatively similar to that of transcription, in the sense that both functions involve splitting the polymer strands as well as the involvement of a polymerase (in this case, DNA polymerase [DNAP] as opposed to RNA polymerase).

DNA Replication Fork

In DNA replication, once again, the two side polymers are separated in a chemical reaction. Basically, 'origins' on the DNA strand (which represent particular 'cued' point for the initiation of replication, are targeted by specific proteins, causing the polymer strands to separate at their base connections.

After that, the replication fork begins, whereby the separated DNA strands are duplicated and joined together, forming two semi-brand new DNA molecules, where previously, there was only one. Once again, the polymerase, known as DNA polymerase 'transcribes' a new polymer strand onto the existing one, pairing up the matching bases for the existing polymer strand, thus creating a new, whole macromolecule.

The Need for Replication

DNA replication is the basis of our genetic inheritancy. It is means means the which DNA, the genetic information storage chemical 'copies' itself (creating a duplicate double helix) and thus is capable of transferring information into a new cell during the process of cellular division.
