Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What describes the process of semi-conservative replication?

  • Both strands are newly synthesized.
  • Each new molecule has one old and one new strand.
  • Only the leading strand is synthesized continuously.

💡 Hint: Recall the definition of semi-conservative replication.

Question 2

True or False: DNA ligase is responsible for unwinding the DNA double helix.

  • True
  • False

💡 Hint: Think about which enzyme has the unwinding function.

Challenge Problems

Push your limits with challenges.

Question 1

Explain the roles of each key enzyme in DNA replication and describe how they interact during the replication process.

💡 Hint: Break the problem down into the sequence of events during replication.

Question 2

If a DNA replication team makes one error for every 1,000,000 nucleotides added, and a human DNA replication involves copying 6 billion nucleotides, what is the expected number of errors?

💡 Hint: Consider the total nucleotides and the error rate.
