Meiosis produces new cell variants, and mitosis proliferates genetically modified cells.
GENETIC ENGINEERING
2
The sister chromatids move to the opposite poles of the cell in .
anaphase
3
is characterized by severe depressive episodes.
Major depressive disorder
4
Chromosome condensation happens in ____. Spindle formation also begins.
prophase
5
is the M phase that leads to the production of either sperm cells or egg cells. This type of division is very closely tied with the process of sexual reproduction.
Meiosis

Cells are usually limited by a certain number of times that they can divide before being too aged to further undergo mitosis. This limit is known as the ____.
Hayflick limit
7
can only occur once the genetic material is properly distributed to the daughter cells.
Cytokinesis

9
The Chromosome DNA in interphase is found in the form of ____ which condenses during mitosis.
chromatin

involves the alignment of the chromosomes in the metaphase plate.
Metaphase
12
46 is the ____ number
diploid
13
The failure of the chromosomes or chromatids to separate properly is known as ____.
nondisjunction
14
interferes with a person's sense of reality.
Schizophrenia
15
begins after the completion of the breakdown of the nuclear envelope.
Prometaphase
16
This stage is named so because it is when the cell synthesizes a copy of its DNA in a very notable process called DNA replication.
Interphase-S
17
In animals, the boundary of the new cells is known as the ____.
cleavage furrow
18
_____ is when the homologous chromosomes in the tetrads exchange segments. This is an event during meiotic division that allows recombination of genes, and ultimately, enhances genetic variation.
Crossing Over
19
23 is the ____ number
haploid
20
ends when two nuclei are formed in the cell.
Telophase
21
can be described according to the number of divisions, number of daughter cells, and the unique events that take place.

, by contrast, is considered the equational division in meiosis because there is no further reduction of the chromosome number in daughter cells.
Meiosis Il
38
check for errors.
Cell cycle checkpoint
