Multiple Choice
In the context of the eukaryotic cell cycle (including DNA replication and mitosis), what is the typical end result of one complete cell cycle starting from a single parent cell?
A
Two genetically different daughter cells, each with double the chromosome number of the parent cell
B
Two genetically identical daughter cells, each with the same chromosome number as the parent cell
C
Four genetically distinct daughter cells, each with half the chromosome number of the parent cell
D
One daughter cell with half the chromosome number of the parent cell
Verified step by step guidance1
Step 1: Understand the phases of the eukaryotic cell cycle, which include interphase (G1, S, G2 phases) and the mitotic phase (mitosis and cytokinesis).
Step 2: Recognize that during the S phase of interphase, DNA replication occurs, doubling the amount of DNA but not changing the chromosome number; each chromosome now consists of two sister chromatids.
Step 3: During mitosis, the sister chromatids are separated into two nuclei, ensuring that each daughter nucleus receives an identical set of chromosomes.
Step 4: Cytokinesis divides the cytoplasm, resulting in two separate daughter cells.
Step 5: Conclude that the end result of one complete cell cycle is two genetically identical daughter cells, each with the same chromosome number as the original parent cell.
