Explanation:
The correct answer is: B)of DNA between homologous chromosomes must happen before metaphase
Mitosis is a process of somatic cell division, whereby a single cell divides into two daughter cells that are genetically identical. There are five stages of mitosis:
1. Interphase- The cell grows and prepares for the division.DNA duplicates, two copies of chromosomes are formed
2. Prophase- duplicated chromosomes condense- become compacted and tightly wound. Mitotic spindle which organize the chromosomes is formed. Chromosomes attach to microtubules.
3. Metaphase-Chromosomes are lined up along the equator of the elongated cell (metaphase plate is formed).
4. Anaphase- the sister chromatids are moving to opposite ends of the elongated cell.
5. Telophase- chromatids are on the opposite ends and cell division is almost over.
The phase after these is cytokinesis where the cell's cytoplasm divides.
