The Cell Cycle
Phases
100
The process that results in new cells with genetic material that is identical to the original cell
What is mitosis
100
The process by which the chromosome number is halved.
What is meiosis?
100
Polar bodies
3 female gametes that do not participate in reproduction
100
The longest phase of the cell cycle. Name each phase included
What is interphase? G1, S, G2
100
This is not a part of mitosis, but occurs after mitosis is done.
What is cytokinesis?
200
Mitosis is related to __________ reproduction
Asexual
200
How is the DNA arranged at the beginning of meiosis? (Hint: the correct answer is NOT just chromosomes)
Homologous chromosomes
200
What is cancer? How does it happen?
Something disrupts the cell cycle (smoking, uv, etc) and the cell divides over and over
200
List this differences between chromatin, chromatid, and sister chromatids.
tin - loose. tid - tight. sisters - two tids together by centromere
200
List what happens in prophase. 3 key things
chromatin --> chromatid. Nuclear envelope breaks down. Spindles form
300
Mitosis creates ______ daughter cells. Each is considered a ________ cell. (Hint: think chromosomes)
2, diploid
300
Meiosis creates ______ daughter cells. Each is considered a ________ cell. (Hint: think chromosomes)
4, haploid
300
Spindle fibers are formed from __________ and attach at the _________ on the chromosome.
Centriole, centromere
300
Name this phase
Metaphase II
300
What is anaphase?
Chromatids (or homologous chromosomes for meiosis) are pulled to opposite poles.
400
This is the location in your body where mitosis takes place (type of cells)
What are body cells or somatic cells?
400
Meiosis for males? Females?
Spermatogenesis, oogenesis
400
The name of reproductive cells
What are gametes?
400
The name of the phase where DNA is replicated.
What is the S phase of interphase?
400
What happens in telophase? 3 key things.
chromatid --> chromatin. Nuclear envelope comes back. Spindles disappear.
500
List all the phases of mitosis in order
prophase, metaphase, anaphase, telophase
500
3 key differences between Meiosis I and Meiosis II
What is separation of homologous pairs VS separation of sister chromatids....... What is crossing over during Meiosis I but not II ......What is interphase before Meiosis I but not II
500
The number of chromosomes at the start of meiosis vs the end of meiosis.
What is diploid? What is haploid?
500
Name this phase
Telophase 2
500
The phase where chromosomes become visible and in Meiosis, crossing over will occur occur.
What is prophase 1?
