Helicase
In which direction does DNA replication occur?
5' to 3'
Where are nucleotides added in the leading strand during DNA replication?
3' end
What does DNA ligase do at the end of DNA replication?

Why is DNA replication considered 'semiconservative'?
Each molecule contains one original DNA strand and one new strand
Test your understanding of the process of DNA replication, including the involvement of enzymes such as helicase and DNA polymerase, and the occurrence during the S phase of the cell cycle. Explore the key steps and concepts in DNA replication.
