    Solution Preview

    Before answering, we need to understand the difference between type I and type II restriction endonucleases. Let's start with some definitions:

    Restriction endonucleases are enzymes that recognize very specific DNA sequences, and then cut at or near the recognition sequence.

    Type I restriction endonucleases cut at sites that ...

    Solution Summary

    This solution is a 213 word document that provides help for students to understand the differences between type I and type II restriction endonucleases (restriction enzymes). It also highlights why molecular biologists use restriction enzymes and why type II restriction endonucleases are more useful to molecular biologists than type I restriction endonucleases.
