DAILY DOUBLE Back
4
This is the stage where chromosomes line up in the center of the cell
metaphase Back
5
This is the stage where chromosomes are formed
prophase Back
6
This is the longest phase of mitosis where the centrosomes are at opposite poles
metaphase Back
7
this is the stage where the nucleolus disappears
prophase Back
8
this is the phase where cohesin proteins are cleaved
anaphase Back
9
This is the stage of meiosis where synapsis takes place
Prophase I Back
10
This is the phase of meiosis where homologous chromosomes separate
Anaphase I Back
11
This is the phase where sister chromatids are lined up in the center of the cell
Metaphase II Back
12
This is the phase in meiosis I where half of the chromosomes are present when compared to prophase I
Telophase I Back
13
This is the stage where microtubules attach to the centromeres of sister chromatids
Metaphase II Back
14
Normal cell cycles are regulated by the presence of these
Growth factors Back
15
Density-dependent inhibition
This is the type of growth where cells can sense that there’s already enough cells surrounding it Density-dependent inhibition Back
16
These are the three checkpoints during the cell cycle
G1, M, G2 Back
17
In order to surpass G2, you need these two proteins to come together to form this
Cyclin + Cdk (cyclin-dependent kinase) = MPF (maturation promoting factor) Back
18
This is the property of many animal cells that must be attached to something before they can grow
Anchorage dependence Back
19
somatic cells mitosis Back
20
interphase both Back
21
reduction division meiosis Back
22
Contains DNA both Back
23
Homologous chromosomes in metaphase
meiosis Back
24
a structure of proteins associated with specific sections of chromosomal DNA at the centromere
kinetochore Back
25
Radial array of short microtubules
aster Back
26
Assembly of spindle microtubules
centromeres Back
27
Shallow groove in the cell surface near the metaphase plate
Cleavage furrow Back
28
Fibers made of microtubules and associated proteins
Mitotic spindle Back
29
a cell containing half the chromosomes of another cell
haploid Back
30
the “vehicles that transmit genes from one generation to the next”
gametes Back
31
chromosomes that each carry genes controlling the same inherited characteristics
homologous Back
32
the “physical manifestation of crossing over”
chiasmata Back
33
proteins that keep chromatids together at anaphase I
Shugoshi, cohesin Back
34
Individual chromosomes that carry genes derived from two different parents
Recombinant chromosomes Back
35
this is the number of autosomal pairs of chromosomes in humans
22 Back
36
This is the stage in which chromosomes are extracted for a karyotype
metaphase Back
37
This is the process of cancer developing and spreading
metastasis Back
38
this is a nondividing stage that some cells such as nerve and muscles stay in
