Give two features of DNA and explain how each one is important in the semi-conservative replication of DNA.

DNA has a number of important features that allow semi-conservative replication to take place. These include:1. DNA bases are held together by weak hydrogen bonds between bases that can be easily broken, allowing the two DNA strands to separate.2. DNA is composed of two complementary strands. Once they have been separated from one another, each strand can act as a template for replication (the production of new DNA). 3. DNA bases will only bind to their complementary base. This allows for accurate DNA replication to take place.
