What is the steps of replication?Show answer
Replication can be described in a few clear steps:
What are two identical molecules?Show answer
The result is two DNA molecules, each made of one original (template) strand and one newly built strand. Because the pairing rule is fixed, each new molecule is identical to the original.
What is q1?Show answer
State what happens to the two strands of DNA at the start of replication. [1 mark]
What is q2?Show answer
Explain the role of each separated strand during replication. [2 marks]
What is q3?Show answer
