Replication is the process where DNA is copied into two daughter DNA.
Basically, during replication DNA is copied into two daughter DNAs so here DNA plays the most important part. Without DNA, replication will not occur
The whole process of replication is catalyzed by various enzymes and proteins. These enzymes can be divided into two categories:
* Replisome and
* DNA Polymerase.
The replication process goes by three processes:
2. Elongation and
The DNA is unzipped and DNA polymerase puts the new complementary base ( A,C,G,U)
