Number of Chromosomes in Human Cell at Difference Stages of Melosis Identify the number of chromosomes in a typical human GERM cell during each stage of meiosis. For each stage, choose either 23 or 46 chromosomes. - Prophase - Metaphase 1 Anaphase - Telophase A 23 - Prophase II B. 46 - Metaphase II - Anaphase 11 - Telophase 11
alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
Experiment 3: Following Chromosomal DNA Movement through Meiosis In this experiment, you will follow the movement of the chromosomes through meiosis I and II to create gam- etes. Materials Procedure Trial 1 As prophase I begins, the replicated chromosomes coil and condense... 1. Build a pair of replicated, homologous chromosomes. 10 beads should be used to create each individual sister chromatid (20 beads per chromosome pair). The five-holed bead represents the centromere. To do this... For example, suppose you start...
