WebLearn how DNA REPLICATES. This goes through DNA replication and what is meant by semi-conservative replication. Learn the role of DNA helicase and DNA poly... WebSemi-conservative DNA replication. During cell division, cells need to make a complete copy of their genetic information. When DNA is replicated, the new DNA molecule is made up of one strand of the original DNA whereas the other strand is made of freshly made DNA. Since half of the DNA is preserved from the previous round of DNA replication, we …
