What is the end result of mitosis in a typical diploid somatic cell?
A
Four genetically distinct haploid cells produced by two rounds of division
B
Two genetically different diploid daughter cells due to crossing over during prophase
C
One diploid cell with twice the normal amount of DNA because cytokinesis does not occur
D
Two genetically identical diploid daughter cells with the same chromosome number as the parent cell
검증된 단계별 안내1
Recall that mitosis is a process of cell division that results in two daughter cells from a single parent cell, primarily for growth and tissue repair in diploid somatic cells.
Understand that during mitosis, the parent cell's chromosomes are duplicated during the S phase of interphase, so each chromosome consists of two sister chromatids before mitosis begins.
During mitosis, the sister chromatids are separated into two nuclei, ensuring that each daughter cell receives an identical set of chromosomes.
Recognize that the chromosome number remains the same in the daughter cells as in the parent cell, meaning if the parent cell is diploid (2n), each daughter cell is also diploid (2n).
Conclude that the end result of mitosis is two genetically identical diploid daughter cells, each with the same chromosome number as the original parent cell.
