cell division

cell division  

Reference type:
Overview Page
Reproduction of cells by division first of the chromosomes (karyokinesis) and then of the cytoplasm (cytokinesis). Cell division to produce more body (somatic) cells is by mitosis; cell division ...
diakinesis

diakinesis  

Reference type:
Overview Page
n. the final stage in the first prophase of meiosis, in which homologous chromosomes, between which crossing over has occurred, are ready to separate.
diplotene

diplotene  

Reference type:
Overview Page
n. the fourth stage in the first prophase of meiosis, in which crossing over occurs between the paired chromatids of homologous chromosomes, which then begin to separate.
gametogenesis

gametogenesis  

Reference type:
Overview Page
n. the process by which spermatozoa and ova are formed. In both sexes the precursor cells undergo meiosis, which halves the number of chromosomes. However, the timing of events and the size and ...
heterotypic

heterotypic  

Reference type:
Overview Page
Describing an interaction between dissimilar things; e.g. heterotypic adhesion is adhesion between different cell types.
karyokinesis

karyokinesis  

Reference type:
Overview Page
n. division of the nucleus of a cell, which occurs during cell division before division of the cytoplasm (cytokinesis). See mitosis.
leptotene

leptotene  

Reference type:
Overview Page
n. the first stage in the first prophase of meiosis, in which the chromosomes become visible as single long threads.
meiotic spindle

meiotic spindle  

Reference type:
Overview Page
The equivalent of the mitotic spindle in meiosis.
pachytene

pachytene  

Reference type:
Overview Page
The period in the first prophase of meiosis when paired homologous chromosomes are fully contracted and twisted around each other.
zygotene

zygotene  

Reference type:
Overview Page
The second phase of the first prophase of meiosis, in which pairing (synapsis) of homologous chromosomes takes place. Intimate contact is made between identical regions of homologues, in a process ...
