What are the three reasons that cells divide?
Growth, repair, and reproduction
100
How many cells are produced at the end of mitosis?
2 identical cells
100
What is crossing over and when does it occur?
Crossing over is when two chromosomes switch genetic information and it occurs during prophase I.
100
What is the name of the location where a spindle fiber attaches to a chromosome?
Centromere
100
True or false: The cells that result from meiosis are genetically identical to each other.
False
200
What are the three phases of the cell cycle?
Interphase, mitosis, cytokinesis
200
Which phase is shown in the photo below?
Metaphase
200
How many cells result from meiosis and how many chromosomes are in each cell?
4 cells, 23 chromosomes in each cell
200
Gametes have how many chromosomes?
23
200
What happens during interphase?
The cell grows, the DNA duplicates, and the cell prepares for division
300
How many chromosomes do body cells have?
46
300
During which phase of mitosis do the chromatid separate and get pulled to opposite sides of the cell?
Anaphase
300
Which phase is shown in the image?
Anaphase II
300
What are homologous chromosomes?
Chromosomes that have the same size, shape, and genetic information.
300
Which phase of meiosis is shown in the image?
Prophase II
400
Why is it important for the DNA to be copied during interphase?
The daughter cells would not have the correct number of chromosomes if the DNA was not copied
400
Which phase is shown in the photo below?
Telophase
400
Which phase of meiosis is shown in the image?
Telophase I / Cytokinesis
400
What is the difference between diploid cells and haploid cells?
Diploid cells have two copies of each chromosome while haploid cells only have one copy of each chromosome.
400
Which phase of meiosis is shown in the image?
Telophase II / Cytokinesis
500
What is the longest phase of the cell cycle?
Interphase
500
During which phase of mitosis do chromosomes first become visible under a microscope?
Prophase
500
Which phase is shown in the following image?
Metaphase I
500
How are chromatids and chromosomes related to each other?
Two chromatids make up a chromosome.
500
How is metaphase in mitosis different from metaphase I in meiosis?
In metaphase I of meiosis, the chromosomes are lined up next to their homologous pair, but they do not do this in mitosis.
