Document Summary
Cell plate: formation of plant cells. Cyclin: a protein that varies in concentration depending on the cell cycle. Cdk: cyclin dependent kinase, remains in constant concentration. Ploidy refers to the number of sets of chromosomes. Polypoid more than 2 sets of chromosomes. In g2 the sister chromatids in a single replicated chromosomes are. Prophase i: homologous chromosomes in synapsis, tetrad formation = 4 chromatids, chiasmata = tetrad connected with each other, crossing-over, after crossing-over, sister chromatids are no longer identical. A cell in anaphase ii will have how much dna compared to when it was in prophase. Cell in 2nd division will always have half as much in 1st division. A cell in g1 of the cell cycle contains a total of 6 chromosomes in 3 homologous pairs. Two important events: segregation, the homologous chromosomes separate into different daughter cells. Independent assortment: the pairs of chromosomes assort independently from one another, different outcomes.
