The process during which the nucleus of a cell is divided into two nuclei is known as____________.
a
mitosis
b
S Phase
c
G1
d
cytokinesis
d. cytokinesis
The correct answer is d) cytokinesis. Cytokinesis is the process in cell division where the cytoplasm of a cell divides to form two daughter cells, each with its own nucleus.
To arrive at this answer, we can eliminate options a) mitosis, b) S Phase, and c) G1, as they are not directly related to the process of dividing the nucleus into two nuclei. Here is a brief explanation of what these options refer to:
a) Mitosis: Mitosis is the process in cell division responsible for the division and distribution of the replicated chromosomes into two daughter cells. It occurs after the nucleus has duplicated its DNA during the S Phase of the cell cycle.
b) S Phase: The S Phase is the stage of the cell cycle where the DNA within the nucleus undergoes replication, resulting in two complete sets of DNA.
c) G1: G1 is the first phase of the cell cycle where the cell grows and prepares for DNA replication.
Considering the remaining option d) cytokinesis, it specifically describes the process of dividing the cellular content including the cytoplasm and organelles to create two separate daughter cells, each containing its own nucleus. Therefore, cytokinesis is the most appropriate term for the described process.
