1) A tissue in a mouse contains two types of cells: one that divides rapidly and one that divides more slowly. The most likely difference between these two cell types is that the slow-dividing cell type spends more time in phase G1, G2, G3, M, or S 2) In meiosis II a- four genetically identical cells are generated b- sister chromatids are separated c- DNA replication occurs d- crossing over occurs e- both a and b 3) The four haploid nuclei found at the end of meiosis differ from one another in their exact genetic composition. Some of this difference is the result of? a- cytokinesis b- replication of DNA during the S phase c- separation of sister chromatids at anaphase II d- spindle formation e- crossing over during prophase I 4) Which of the following does not occur during mitotic prometaphase? a- disappearance of the nuclear envelope b- initial movement of chromosomes towards the equatorial plate c- adhesion of chromatids at the centromere d- pairing of homologous chromosomes e- disappearance of the nuclei
