Unit 3.2 How do organisms inherit traits?

Open Ended

Describe the relationship between chromosomes, DNA, and genes.

Multiple Choice

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.
