A stage of mitosis is shown in the diagram. Which stage is it and what are its characteristics?


 
1. Metaphase-spindle fibers attached to kinetochores, centromeres split and chromatids separate
2. Metaphase- chromosomes moved to spindle equator chromosomes made up of two sister chromatids
3. Anaphase - centromeres split and chromatids separate and start moving away
4. Late prophase - chromosomes move to spindle equator

Select the correct option with respect to mitosis.
 
1. Chromatids start moving towards opposite poles in telophase.
2. Golgi complex and endoplasmic reticulum are still visible at the end of prophase.
3. Chromosomes move to the spindle equator and get aligned along the equatorial plate in metaphase.
4. Chromatids separate but remain in the center of the cell in anaphase.
