Write True or False 1. In prophase of mitosis the chromosomes condense in y sharp structure that can be easily seen under microscope 2. In interphase stage of mitosis a membrane forms around each set of chromosomes to create two new nuclei 3. In interphase l of meiosis, the paired chromosomes line up 4. In prophase ll of meiosis, it is visibly obvious that replication has not occurred 5. In telophase l of meiosis, the cell pinches and divides 6. Homologous chromosomes contain the unmatched alleles donated from mother and father 7. In anaphase of mitosis, the sister chromatids are pulled apart by the mitotic spindle which pulls one chromatid to one pole and the chromatid opposite pole 8.At the end of the prophase in mitosis, the membrane around the nucleus in the cell dissolves away releasing the chromosomes. 9.During interphase in mitosis, microtubules extend from centrosomes. 10.If not corrected in time, mistakes made during mitosis can result changes in DNA but will not lead to…
