Only some cells derive from a mitosis event.. 1. Which statement is most correct regarding the difference between mitosis and meiosis? O Meiosis can produce any cell type, while mitosis can only make gametes (sperm/egg cells) * Mitosis essentially clones a cell (makes an identical copy), while meioisis is a ma O complex process that divides up a cell's set of chromosomes into gametes (sperm/egg cells) ODNA replication is required for mitosis but not for meiosis ODyads are seen in mitosis but not meiosis 2 What distinguichon hon
ala Marked out of 1 Select one: OA. A Tissue Sample of Unknown Organism OB. B OC C D. D d. b. Mitosis must be carefully regulated to ensure the normal distribution of chromosomes to the daughter cells. A ring-shaped protein molecule known as cohesin attaches to the centromere of a chromosome and holds sister chromatids together to prevent their premature separation. Enzymes detach cohesin molecules from the centromere immediately before the sister chromatids segregate. -based on Nature, 2006 In which of the cells labelled in the diagram above are enzymes most likely acting to detach cohesin molecules from the centromere?
