Multiple Choice
During mitosis in eukaryotic cells, what is the primary outcome for the nucleus and chromosomes?
A
Homologous chromosomes pair and exchange segments by crossing over.
B
DNA is replicated to produce two identical copies of each chromosome.
C
Sister chromatids separate and are distributed into two genetically identical daughter nuclei.
D
The cell divides its cytoplasm to form two separate daughter cells (cytokinesis).
Verified step by step guidance1
Understand the phases of mitosis and their key events, focusing on what happens to the nucleus and chromosomes during this process.
Recall that mitosis is the division of the nucleus, resulting in two nuclei that are genetically identical to the original nucleus.
Recognize that during mitosis, sister chromatids (which are identical copies of a chromosome formed during DNA replication) separate and move to opposite poles of the cell.
Note that homologous chromosomes pairing and crossing over occur during meiosis, not mitosis, so this is not the primary outcome in mitosis.
Conclude that the primary outcome of mitosis is the separation of sister chromatids into two genetically identical daughter nuclei, preparing the cell for cytokinesis.
