Question

question 7
in which stage of the cell cycle does dna replication occur?
metaphase
anaphase
prophase
interphase

question 8
mitosis creates _____ from one parent cell.
four identical daughter cells
two identical daughter cells
two genetically different daughter cells
four genetically different daughter cells

Explanation:

Identify the stage of DNA replication

Using the DNA Replication and Cell Cycle Phases knowledge points:

• DNA replication occurs during the S (synthesis) phase of the cell cycle.
• The S phase is a sub-phase of Interphase, which also includes the \(G_1\) and \(G_2\) phases.
• Metaphase, anaphase, and prophase are stages of mitosis (M phase), which occurs after DNA replication is complete.
• Therefore, DNA replication occurs during interphase.

Determine the outcomes of mitosis

Using the Mitosis Outcomes knowledge point:

• Mitosis is a process of asexual cell division where a single somatic cell divides.
• It results in the formation of two genetically identical diploid daughter cells.
• This ensures that each new cell receives an exact copy of the parent cell's genetic material.
• Therefore, mitosis creates two identical daughter cells from one parent cell.

Answer:

Question 7

• metaphase
• anaphase
• prophase
• interphase (Correct answer)

Question 8

• four identical daughter cells
• two identical daughter cells (Correct answer)
• two genetically different daughter cells
• four genetically different daughter cells
