Multiple Choice
In mitosis, are the daughter cells genetically identical to the parent cell (assuming no mutations occur)?
A
No; mitosis produces four genetically distinct daughter cells due to crossing over.
B
No; mitosis halves the chromosome number to produce haploid daughter cells.
C
Yes; mitosis produces two daughter cells with the same chromosome number and genetic information as the parent cell.
D
Yes; but only if DNA replication occurs after cytokinesis rather than before mitosis.
Verified step by step guidance1
Understand the purpose of mitosis: Mitosis is a type of cell division that results in two daughter cells, each genetically identical to the parent cell, maintaining the same chromosome number.
Recall the chromosome number during mitosis: The parent cell duplicates its DNA during the S phase of interphase before mitosis begins, so each chromosome consists of two sister chromatids.
Recognize that during mitosis, sister chromatids separate and are distributed equally to the two daughter cells, ensuring each daughter cell receives an identical set of chromosomes.
Contrast mitosis with meiosis: Unlike meiosis, mitosis does not involve crossing over or reduction of chromosome number; meiosis produces four genetically distinct haploid cells, while mitosis produces two genetically identical diploid cells.
Conclude that, assuming no mutations occur, mitosis produces two daughter cells genetically identical to the parent cell, both in chromosome number and genetic information.
