third stage of mitosis when chromatids are separated to opposite poles of the cell.
anaphase
1 of 17
the highly ordered sequence of events that takes place in a cell, resulting in division of the nucleus and the formation of two genetically identical daughter cells.
cell cycle
2 of 17
region at which two chromatids are held together.
centromere
3 of 17
control mechanisms of the cell cycle.
checkpoints
4 of 17
sections of DNA, which became entangled during crossing over, break and rejoin during anaphase 1 of meiosis sometimes resulting in an exchange of DNA between bivalent chromosomes, forming recombinant chromatids and providing genetic variation.
chiasmata
5 of 17
two identical copies of DNA (a chromosome) held together at a centromere.
chromatids
6 of 17
uncondensed DNA in a complex with histones.
chromatin
7 of 17
cell division stage in the mitotic phase of the cell cycle that results in the production of two identical daughter cells.
cytokinesis
8 of 17
half the normal chromosome number; one chromosome of each type.
haploid
9 of 17
proteins that form a complex with DNA called chromatin.
histones
10 of 17
the arrangement of each homologous chromosome pair (bivalent) in metaphase 1 and metaphase 2 of meiosis is independent of each other and results in genetic variation.
independent assortment
11 of 17
growth period of the cell cycle, between cell divisions (mitotic phase). Consists of stages G1, S and G2.
interphase
12 of 17
form of cell division where the nucleus divides twice (meiosis I and meiosis II) resulting in a halving of the chromosome number and producing four haploid cells from one diploid cell.
meiosis
13 of 17
nuclear division stage in the mitotic phase of the cell cycle.
mitosis
14 of 17
period of cell division of the cell cycle. Consists of the stages mitosis and cytokinesis.
mitotic phase
15 of 17
first stage of mitosis when chromatin condenses to form visible chromosomes and the nuclear envelope breaks down.
prophase
16 of 17
fourth stage of mitosis when chromosomes assemble at the poles and the nuclear envelope reforms.
telophase
17 of 17
