About This Quiz & Worksheet

DNA replication is a complicated science involving several processes and components, and this quiz/worksheet will help you test your understanding of them.

Quiz & Worksheet Goals

In these assessments you'll be tested on the DNA components and processes of:

  • Replication forks
  • The lagging strand
  • RNA primers
  • Replication bubbles
  • DNA polymerase

Skills Practiced

  • Reading comprehension - ensure that you draw the most important information from the related biology lesson
  • Information recall - access the knowledge you've gained regarding replication forks
  • Knowledge application - use what you have learned to identify what happens to replication bubbles in order to complete replication

Additional Learning

To learn more, review the lesson titled DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands. This lesson covers the following objectives:

  • Understand the term semi-conservative in relation to DNA replication
  • Define and identify the respective functions of the DNA helicase, RNA primase, polymerase, and an Okazaki fragment
  • Differentiate between leading and lagging strands
