When cells stop dividing in order to specialize in structure and function.
What is differentiation?
200
The first stage of mitosis.
What is prophase?
200
The process in which chromosomes exchange genetic information.
What is crossing over?
200
The purpose of asexual reproduction.
What is regeneration and reproduction?

300
Offspring are genetically ________.
What is different?
400
Molecular signals that can control cell division.
What are cell cycle regulators?
400
The stage of mitosis in which separated chromatids are pulled to opposite ends of the cell.
What is anaphase?
400
Relaxed strands of DNA.
What is chromatin?
400
Offspring are genetically _______.
What is identical?
400
Independent assortment of chromosomes, crossing over, gametes are genetically unique, two parents contribute chromosomes, and diverse populations are less affected by viruses and environmental changes.
