Alignment of chromosomes in the center of the cell at the equatorial plate constitutes which stage of mitosis?

Alignment of chromosomes in the center of the cell at the equatorial plate constitutes which stage of mitosis? Correct Answer Metaphase

The correct answer is Metaphase.

Key Points

  • Mitosis is a kind of cell division in which one cell (the mother) divides to generate two genetically identical new cells (the daughters).
  • Mitosis is the stage of the cell cycle's division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
  • Mitotic divisions are a mode of reproduction for single-celled eukaryotes like yeast, contributing new individuals to the population.
  • Phases of mitosis:
  • Interphase:
    • In preparation for cell division, the DNA in the cell is replicated, resulting in two identical full sets of chromosomes.
    • Two centrosomes, each comprising a pair of centrioles, are located outside of the nucleus and are essential for cell division.
    • Microtubules extend from these centrosomes during interphase.
  • Prophase:
    • Under a microscope, the chromosomes condense into X-shaped structures that are plainly visible.
    • Each chromosome is made up of two sister chromatids, each of which contains the same genetic material.
    • The chromosomes are paired up so that both copies of chromosome 1 are together, and so forth.
    • The membrane around the nucleus in the cell dissolves at the conclusion of the prophase, freeing the chromosomes.
    • The mitotic spindle, which is made up of microtubules and other proteins, spans the cell and connects the centrioles as they travel to opposite poles.
  • Metaphase:
    • The chromosomes are perfectly lined up end-to-end along the cell's equator.
    • The mitotic spindle threads extend from the centrioles, which are now at opposing poles of the cell.
    • The sister chromatids are connected by the mitotic spindle threads.
  • Anaphase: 
    • The mitotic spindle then pulls the sister chromatids apart, pulling one chromatid to one pole and the other chromatid to the opposite pole.
  • Telophase: 
    • A complete pair of chromosomes assemble at each cell pole.
    • To build two new nuclei, a membrane forms surrounding each set of chromosomes.
    • The single-cell then pinches in the middle, separating into two daughter cells, each with a nucleus and a full set of chromosomes. Cytokinesis is the name for this process.
