CELL DIVISION

MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The phase of mitosis, meiosis I, or meiosis II that is characterized by the arrangement of all chromosomes along the equator of the cell is called:
A
telophase
B
metaphase
C
anaphase
D
prophase
Explanation: 

Detailed explanation-1: -During metaphase, all of the chromosomes are aligned in a plane called the metaphase plate, or the equatorial plane, midway between the two poles of the cell.

Detailed explanation-2: -Metaphase. Next, chromosomes assume their most compacted state during metaphase, when the centromeres of all the cell’s chromosomes line up at the equator of the spindle.

Detailed explanation-3: -Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell.

Detailed explanation-4: -During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane.

Detailed explanation-5: -Meiosis II is the second division of meiosis. It occurs in both of the newly formed daughter cells simultaneously. Meiosis II is similar to Mitosis in that the sister chromatids are separated.
