• B. Binary fission
• C. Apoptosis
• D. Meiosis

Answer: (A)

Verified step by step guidance

1. Understand the question: The problem asks which process results in a daughter cell containing the same DNA as its parent cell. This means the process must involve the replication and equal distribution of genetic material to ensure identical DNA in the daughter cells.
2. Review the processes listed: Mitosis, Binary fission, Apoptosis, and Meiosis. Each of these processes has a distinct role in cellular biology.
3. Analyze Mitosis: Mitosis is a process of cell division in eukaryotic cells where the parent cell divides to produce two genetically identical daughter cells. This involves DNA replication during the S phase of the cell cycle, followed by segregation of chromosomes during mitosis.
4. Analyze Binary fission: Binary fission is a process used by prokaryotic cells (like bacteria) to divide. It also results in two genetically identical daughter cells, but it is specific to prokaryotes and simpler than mitosis.
5. Eliminate incorrect options: Apoptosis is programmed cell death and does not involve cell division. Meiosis, on the other hand, is a process that produces gametes (sperm and egg cells) with half the genetic material of the parent cell, so it does not result in identical daughter cells. Therefore, the correct processes are Mitosis (for eukaryotes) and Binary fission (for prokaryotes).
