A researcher examining a root tip observes a plant cell with condensed sister chromatids, kinetochores with attached microtubules, and individual chromosomes that are aligned at the equatorial plate of the cell. Which of the following best describes what the next process will be in the cell?
answer choices
a) Homologous chromosomes (each with two sister chromatids) will move toward opposite poles of the cell.
b) Paired chromatids will separate, and the new daughter chromosomes will move toward opposite poles of the cell.
c) The nuclear envelope will break down, and the spindle will begin to form.
d) The chromatin will decondense, and the daughter cell will enter interphase.

Respuesta :

Answer:

Option (b).

Explanation:

Mitosis is a type of cell division in which a single parent cell is divided into two daughter cell with equal number of chromosomes. This is also known as reduction division.

The chromosomes alignment at the middle plate describe that this stage is metaphase. After completing the metaphase, the chromosome enters at anaphase stage. In this stage, the separation of sister chromatids start and the they moves towards the opposite pole.

Thus, the correct answer is option (b).
