Study online at quizlet.com/_x8phn
1.
anaphase
phase of mitosis in which the mitotic
spindle pulls the sister chromatids to
opposite ends of the cell
2.
anaphase II
Part of meiosis similar to Mitosis
where The sister chromatids are
spearated at their centromeres and
pulled to opposite sides of the cell.
homologous
pair
a pair of chromosomes, one from each parent,
that have relatively similar structures and
gene values
24.
I, M, C
Cell Cycle Order
25.
interphase
the longest period of the cell cycle that
includes G1, S, and G2; when cell is preparing
for division
26.
malignant
cancer tumor
27.
meiosis
cell division that produces reproductive cells
in sexually reproducing organisms-
28.
meiosis cells
creates four new sex cells with a haploid
amount of chromosomes; cuts chromosomes
in half
29.
Meiosis I
cuts chromosome number in half
30.
metaphase
phase of mitosis where the chromosomes line
up in the middle of the cell and attach to the
mitotic spindle
31.
metaphase I
chromosomes line up down the middle in
double file
23.
3.
asexual
one cell forms two
4.
benign
non cancerous tumor
5.
cancer
disease in which some of the body's
cells multiply uncontrollably
6.
cell cycle
includes interphase, m phase, and
cytokinesis
7.
cell division
makes multiple copies of cell
8.
centriole
connects to spindle and move appart
during prophase
9.
centromere
holds sister chromatids together
10.
chromatids
two sides of chromosomes
11.
chromosome
full X
32.
metaphase II
12.
clevage
a furrow of the cell that happens during
telophase
phase of meiosis similar to mitosis where
chromosomes line up in the middle
33.
Mitosis
stage of cell cycle in which nucleus divides;
includes PMAT
34.
mitosis cells
creates two identical daughter cells
mitotic
spindle
made from microtubules
36.
nucleus
during the cell cycle this organelle is visible
during interphase and and telophase
37.
PMAT
Mitosis Order
38.
prophase
chromosomes condense and become visible;
nuclear envelope disappears, spindle forms,
centrioles move apart
39.
prophase I
stage of meiosis where where tetrads (a set of
two tightly bound chromosomes) are formed
and may cross over
reasons for
meiosis
to prepare to form a new organism
Reasons for
mitosis
to replace cells that die and for growth
S phase
part of interphase in which cell DNA is
replicated
sexual
reproduction
two cells to one
44.
somatic
body cells that undergo mitosis
45.
telophase
stage of mitosis where spindle disappears,
and nuclear envelope reforms
13.
crossing over
when chromosomes in a tetrad swap
pieces of each other
14.
cytokinesis
process by which the cytoplasm of a
cell divides
15.
daughter cells
new cells produced by cell division
16.
diploid
body cells/somatic cells have the
________ 2N
17.
18.
for growth, to
replace dead cells,
and to prepare for
reproduction
why do cells reproduce?
G1 phase
part of interphase in which the cell
undergoes the most growth
organelles replicate, and cell doubles in
size
19.
G1, S, G2
Interphase order
20.
G2 phase
stage of interphase in which the cell
prepares for mitosis; enzymes and
other proteins made
21.
22.
gametes
haploid
cells produced by meiosis; another
name for sex cells
sperm and eggs contain the _______
N number
35.
40.
41.
42.
43.
46.
telophase I
results in two daughter cells with half the number of chromosomes
47.
tetrad
homologous pairing consisting of four chromatids
