daughter cells have the genetic information to produce enzymes and
other proteins. How is DNA replicated? Answer semiconservative
replication. In Semi conservative replications the enzyme DNA helicase
breaks the hydrogen bonds linking the base…

The importance of mitosis & producing identical daughter cells
1. Growth
2. Differentiation ­ specialised cells can be replicated exactly to produce tissues
that function efficiently
3. Repair ­ mitosis allows repaired tissues to function as well as they did prior to
damage

The cell cycle has three stages:
