DNA is duplicated during this stage.
What is S phase
100
During this phase of mitosis the nuclear envelope breaks down.
What is prophase
100
These proteins help to regulate the cell cycle
What are cyclins
100
What is a tetrad
What is when homologous chromosomes overlap
100
Mitosis creates _____ identical daughter cells
What is two
200
In the onion root lab, in which phase were most cells?
What is Interphase
200
This structure holds two sister chromatids together
What is a centromere
200
These cells have the potential to develop into other cell types
What are stem cells
200
These are two sets of chromosomes, one from each parent
What are homologous chromosomes

300
This is a disorder in which cells have lost control of their growth
What is cancer
300
This is when crossing over occurs
What is Prophase 1 of meiosis
300
This is an advantage of sexual reproduction
What is genetic diversity
400
How is sexual reproduction different on a cellular level than asexual
What is sexual reproduction involves fusing of two cells
400
This is DNA tightly coiled around special proteins called histones
What is chromatin
400
These proteins stimulate division for growth and healing
What are growth factors
400
This is a picture of someone's Chromosomes and can be used to diagnose genetic disorders and determine gender
What is a karyotype
400
During normal mitotic division a 2N cell with 16 chromosomes will produce __________________
What is 2 identical daughter cells each 2N=16
500
Mitosis is the division of this
What is the nucleus
500
A key difference in cytokinesis of animal and plant cells is this
What is that plant cells form a cell plate which eventually develops into membrane and then a cell wall develops.
500
This is programed cell death
What is apoptosis
500
This is a fertilized egg
What is a zygote

How does meiosis differ in males and females?
What is meiosis in males creates 4 sperm cells. In females it creates one egg and three polar bodies
