This website focuses on how the replication fork and associated proteins work together spatially and temporally to make copies of DNA. Richard Losick has put together a simple, but elegant visual learning tool.
Type of Material:
This could be useful as a visual tool during a lecture on DNA replication or alternatively by sudents as a supplemental activity.
Adobe Flash. It works fine in Firefox, Safari and Internet Explorer.
Identify Major Learning Goals:
Although these are not clearly stated on the website, it will help students to visualize and better understand the processes involved in DNA replicaiton.
Target Student Population:
High school biology and undergraduate biology students interested in the molecular world.
Prerequisite Knowledge or Skills:
An introductory knowledge of DNA and enzymes as biomolecules would be beneficial.
Evaluation and Observation
Focused on a specific content area
Website seems to easily play on multiple platorms and does not require any special programs or hardware
Good quality graphics are used
Pause, play, forward and backward controls for stepping through the animation
The animation provides a simplistic overview to help students understand the basic processes involved in DNA replication
The site provides only basic details about the "replication fork" and does not provide much information about the origin of replication
Potential Effectiveness as a Teaching Tool
Website would be effective as a supplemental learning tool for college general education courses or high school biology
Could easily replace a lecture covering same topic
Would make an excellent resource in a flipped classroom
Overall extremely effective
May require some background information to be effective
Ease of Use for Both Students and Faculty
As long as Flash Play is functioning well, this website is very easy to use
The first animation automatically plays and the user can pause the animations at any time or click around to see the other animations and descriptions
