Cell division pt 2 Flashcards
what is Anaphase
Chromosomes are separating
Takes a long time
what is Telophase
End up with two cells
Separation of two cells
what is Kinesin
motor proteins that transports the chromosomes microtubules
what is Cytokinesis
Cells divide, two daughter cells
Drugs that inhibit cell division
Inhibitors of microtubules,Inhibitors of microfilaments
Inhibitors of microfilaments are
Taxol
Paclitaxel
Nocodazole
Vinblastine
Inhibitors of microfilaments are
Cytochalasin
Phalloidin
what are sister chromatids
The
replicated forms of a
chromosome joined together
by the centromere.
what is synapsis
Pairing of the
replicated homologous
chromosomes during prophase
I of meiosis
what is crossing over
The exchange of genetic material between non -sister chromatids during synapsis in meiosis I.
what is chiasma
The region of the non - sister chromatids where exchange of the genetic material takes place during Meiosis I (plural chiasmata).
what is meiosis
DNA replications that occurs once in interphase before meosis 1 occurs
number of divisons in meiosis
two, each containing phosphase. metaphaee, anaphase, telephase
synapsis of homologous chromosomes in meiosis
synapsis is unique to meosis; during phropase 1, the homologous chromosomes join along their length forming groups of four chromatins.
number of daughter cells and genetic composition in meiosis
four each haploid containing half as many chromosomes as the parent cells. Genetically nonidentical to parent cell and to each other
