Which of the following is a feature shared by both mitosis and meiosis?

• A. The process results in four daughter cells
• B. Daughter cells are genetically identical to the parent cell
• C. DNA replication occurs prior to cell division
• D. Homologous chromosomes pair and undergo crossing over

Answer: (C)

Verified step by step guidance

1. Understand the context of the question: Mitosis and meiosis are both processes of cell division, but they serve different purposes and have distinct features. Mitosis is involved in growth and repair, producing genetically identical cells, while meiosis is involved in sexual reproduction, producing genetically diverse cells.
2. Review the key steps of mitosis and meiosis: Both processes begin with DNA replication during the S phase of the cell cycle, ensuring that each daughter cell receives the necessary genetic material. This is a shared feature between the two processes.
3. Analyze the options provided: Evaluate each statement to determine if it applies to both mitosis and meiosis. For example, 'The process results in four daughter cells' is specific to meiosis, not mitosis. Similarly, 'Daughter cells are genetically identical to the parent cell' applies to mitosis but not meiosis.
4. Focus on the correct answer: 'DNA replication occurs prior to cell division' is a feature shared by both mitosis and meiosis. This step ensures that the genetic material is duplicated before the division process begins.
5. Clarify why other options are incorrect: 'Homologous chromosomes pair and undergo crossing over' is specific to meiosis during prophase I and does not occur in mitosis. This distinction highlights the unique role of meiosis in generating genetic diversity.
