Q

anaphase

A

During anaphase the centromeres split, separating the two members of each chromatid pair, which move to opposite poles of the cell. Once separated, the chromatids are called chromosomes. As the chromosomes are pulled by the microtubules of the mitotic spindle during anaphase, they appear V‐shaped because the centromeres lead the way and seem to drag the trailing arms of the chromosomes toward the pole.

Q

telophase

A

The final stage of mitosis, telophase, begins after chromosomal movement stops. The identical sets of chromosomes, now at opposite poles of the cell, uncoil and revert to the threadlike chromatin form. A new nuclear envelope forms around each chromatin mass, nucleoli appear, and eventually the mitotic spindle breaks up.

Q

what is the difference between mitosis and meiosis

A
  • Mitosis is the process by which most cells in the body divide, while meiosis is the process by which gametes are produced.
  • Mitosis involves a single round of cell division, while meiosis involves two rounds of cell division.
  • Mitosis produces two identical, diploid daughter cells, while meiosis produces four non-identical, haploid gametes.
  • Mitosis occurs in somatic cells and is essential for growth and repair, while meiosis occurs in germ cells and is essential for sexual reproduction.
