A stage of mitosis is shown in the diagram. Which stage is it and what are its characteristics?
- Metaphase - Spindle fibers attached to kinetochores, centromeres split and chromatids separate.
- Metaphase - Chromosomes moved to spindle equator, chromosomes made up of two sister chromatids.
- Anaphase - Centromeres split and chromatids separate and start moving away.
- Late prophase - Chromosomes move to spindle equator.
The Correct Option is B

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell.
Reason (R): Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus.- NEET (UG) - 2025

Cell Cycle and Cell Division
Cell Cycle:
The sequence of events by which a cell copies itself synthesizes other constituents of the cell and eventually splits into two daughter cells is termed the cell cycle. The cell synthesizes all its constituents in a sequential pattern to make sure the proper division and distribution of components that occurs between the two daughter cells. Therefore, we can say that the cell cycle is the period of time between the development of new daughter cells and their further division.
Stages of Cell Cycle:
The cell cycle can be sub-divided into an additional category of Interphase. Meanwhile, the Interphase can be branched into 3 further stages, such as:
- G1 Phase - “Gap 1 Phase”
- S Phase - "Synthesis Phase"
- G2 Phase - "Gap 2 Phase"

Cell Division:
The division of the parent cells into two or more cells is called daughter cell, cell division takes place. In general, it occurs as a part of a larger cell cycle. All the cell reproduces by dividing into two, wherein each parental cell produces two daughter cells.
Stages of Cell Division:
Cell division can be widely divided into several sub-segments that result from Mitosis and Meiosis.
- Mitosis or (M Phase)
- Meiosis
