meiosis 1 terms Flashcards
1
Q
Synaptomenal Complex (SC)
A
two parallel aligned proteinaceous chromosome cores of a pair of homologous chromosomes at prophase of meiosis. Synaptonemal complexes are meiosis-specific nuclear structures that mediate the tight association between homologous chromosomes.
2
Q
Synapse
A
pair, come together
3
Q
synapsis
A
the fusion of chromosome pairs at the start of meiosis.
4
Q
Bivalents
A
a pair of homologous chromosomes.
5
Q
Chiasmata
A
a point at which paired chromosomes remain in contact during the first metaphase of meiosis, and at which crossing over and exchange of genetic material occur between the strands.
