Multiple Choice
How are mitosis and cytokinesis different in the cell cycle?
A
Mitosis divides the nucleus (separating duplicated chromosomes), while cytokinesis divides the cytoplasm to form two separate daughter cells.
B
Mitosis duplicates the cell's DNA, while cytokinesis separates homologous chromosomes into different nuclei.
C
Mitosis produces four genetically distinct haploid cells, while cytokinesis produces two genetically identical diploid cells.
D
Mitosis occurs only in prokaryotic cells, while cytokinesis occurs only in eukaryotic cells.

Step 1: Understand the definitions of mitosis and cytokinesis within the cell cycle. Mitosis is the process where the cell's nucleus divides, ensuring that duplicated chromosomes are separated into two nuclei.
Step 2: Recognize that cytokinesis is the process that follows mitosis, where the cytoplasm of the cell divides, physically separating the cell into two distinct daughter cells.
Step 3: Note that mitosis focuses on the division of genetic material (chromosomes), while cytokinesis focuses on dividing the cell's cytoplasm and organelles.
Step 4: Clarify that mitosis results in two nuclei with identical genetic information, and cytokinesis completes cell division by producing two separate cells, each with one nucleus.
Step 5: Use this understanding to evaluate the answer choices, identifying that the correct distinction is that mitosis divides the nucleus (separating duplicated chromosomes), while cytokinesis divides the cytoplasm to form two separate daughter cells.
