Quiz: How Well You Know DNA Replication?

How well you know DNA replication? DNA stores the information needed to build and control the cell. The transmission of this information from mother to daughter cells is called vertical gene transfer, and it occurs through the process of DNA replication. What is needed for the process of replication to take place? Well, take this quiz and see how much do you know!
