DNA Structure And Replication Quiz Challenge
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. Test your knowledge of this topic by taking the quiz below.
