Numbers
100
What are the two parts of the cell cycle?
Interphase, mitosis
100
In which phase are chromosomes lined up on the equator?
Metaphase
100
How many times does cytokinesis occur in meiosis?
Two times
100
What keeps the sister chromatids attached to each other?
Centromere
100
What is the difference between haploid and diploid?
Haploid = one set of chromosomes, Diploid = two sets of chromosomes
200
The cell spends most of its time in this part of the cell cycle
Interphase
200
When are sister chromatids pulled apart?
Anaphase
200
What is synapsis?
Homologous chromosomes find pair
200
When are sister chromatids made?
S-phase
200
Use 'n' to describe the daughter cells made after mitosis

Describe the two checkpoints in Interphase
G1 checkpoint - checks for growth and nutrients. G2 checkpoint - checks for DNA replication errors.
300
When does the cleavage furrow form?
Telophase
300
What is the purpose of crossing over?
Exchange genes to make diversity in chromosomes
300
What is the difference between a centromere and a kinetochore?
Centromere keeps chromatids together, kinetochore is a part of the centromere where spindle attaches
300
What is the end product of meiosis?
Four haploid gametes
400
The part of interphase where the cell prepares to divide
G2
400
This phase is the reverse of telophase
Prophase
400
What is the purpose of meiosis?
Make gametes
400
What do we call DNA during Interphase?
Chromatin
400
If an eye cell of a fish contains 12 chromosomes, how many chromosomes are in the egg cells of that fish?
6
500
The part of the cell cycle where the cell divides into two daughter cells
Cytokinesis
500
What is the main difference between mitosis in plant cells and animal cells?
Animals - actin, cleavage furrow. Plants - cell plate
500
Describe the difference between Anaphase I and Anaphase II
Anaphase I - homologous pairs are separated. Anaphase II - sister chromatids are separated.
500
What do we call one half of a duplicated chromosome?
Sister chromatid
