1 the cell cycle are these cells in? Be sure to hide the Interphase What are the two Chromatids halves of a called? By definition, which cells have ½ the total number of s? Haploid the cell cycle is this cell in? Be Metaphase What is created during the S stage of Interphase? DNA (chromatin) What is the 46 human diploid number?
2 Which process produces 4 haploid cells? Meiosis the cell cycle is this cell in? Be Prophase Which parts attach and pull s during mitosis and meiosis? i Spindle fibers Does this karyotype show a boy or girl? Be Answer: Boy the cell cycle is this cell in? Be Telophase What is the 23 human haploid number?
3 What is the linear, string form of DNA called? Chromatin Which cellular process creates somatic cells? Mitosis the cell cycle is this cell in? Be Anaphase What is this picture called? Be sure to hide the Karyotype If there are pairs of s in a fish, how many s do skin cells contain? Name the two separate halves of the meiosis process. Meiosis I and Meiosis II
4 Which process takes place in the testes? Spermatogenesis (meiosis i is too vague) Is this a diploid or haploid karyotype? Be Diploid In order, name the stages of mitosis. Prophase, Metaphase, Anaphase, Telophase Which objects create the zygote? Egg and sperm (Interphase is not a stage of mitosis) Which cells use the cell plate during cytokinesis? Plant cells If there are pairs of chicken s, what is the haploid number? 40 pairs means a total of 80 s. Haploid is when there are ½ the total number.
