The graph illustrates measurements recorded during one mitotic cell cycle. Which stage of mitosis starts at X, and what measurements are represented by curves 1 and 2?
- Aanaphase; distance between centromeres of chromosomes and poles of spindle = 1; distance between centromeres of sister chromatids = 2
- Banaphase; distance between centromeres of chromosomes and poles of spindle = 2; distance between centromeres of sister chromatids = 1
- Cmetaphase; distance between centromeres of chromosomes and poles of spindle = 1; distance between centromeres of sister chromatids = 2
- Dmetaphase; distance between centromeres of chromosomes and poles of spindle = 2; distance between centromeres of sister chromatids = 1
