Module 5 Cell Division
Lesson 3.5.5
Lesson 5—Cell Cycle Disorders and Genetic Testing
Get Focused
Chromosome replication and separation does not always go according to the patterns you’ve learned. Occasionally, the process falters, and the results can be dramatic. In this lesson, you will learn of common disorders resulting from improper cell division and consider the ethical issues involved in prenatal tests and working with embryonic cells.
In this lesson, the following focusing questions will be examined:
- How do chromosome disorders occur, and does their frequency increase with the age of the parent individual?
- How can embryonic cells be used, and what technologies exist to test the genetic condition of an unborn fetus, thereby allowing parents to know about the condition of their child prior to birth?
This lesson will take approximately 60 minutes to complete, but you will need an additional 60 minutes for work on the assessment projects.
