Unit 3: Molecular Genetics - Lesson 5 1.0

Question 1

What determines how different types of cells are created and maintained?

Answer 1

Differential gene expression.

Question 2

Do all cells in a person have the same genetic information?

Answer 2

Yes, all 100 trillion cells of any one person have the same genetic information.

Question 3

How do different cells use the same genetic blueprint?

Answer 3

Different cells use the same blueprint in different ways.

Question 4

How does the control of gene expression occur?

Answer 4

by regulating the flow of information from DNA to protein.
