Module 7 Lesson 2 - 1

Get Focused

The DNA from the single original cell must be replicated as the cell divides. Mistakes in this replication process can be life-threatening. In Lesson 1, you learned the structure of DNA. This structure allows for a fantastic way of copying all hereditary information of the cell called DNA replication.

In Lesson 4, you will learn that this process is not perfect. Mistakes occur. Could superheroes be created through these mistakes? Keep this question in mind as you move through the lesson.

This lesson addresses the following focusing questions:

• How does DNA code our genetic message?

• How do new cells get a copy of this message?
