What does the term 'mitosis' refer to?

• A. The preparation for cell division
• B. The phase of DNA replication
• C. The division process of the cell into two daughter cells
• D. The synthesis of mRNA

Answer: (C)

The term 'mitosis' specifically refers to the process by which a single cell divides to produce two genetically identical daughter cells. This process is essential for growth, development, and tissue repair in multicellular organisms. During mitosis, the chromosome number is maintained as the DNA is duplicated and evenly distributed into the two new cells. The phases of mitosis include prophase, metaphase, anaphase, and telophase, each characterized by distinct events that lead to the successful separation of the duplicated chromosomes.

In contrast, the other options pertain to different processes related to the cell cycle and molecular biology. One option describes the preparatory phase before cell division, which involves various preparations for mitosis but does not constitute the actual process. Another focuses on DNA replication, which occurs prior to mitosis and is crucial for ensuring that each daughter cell receives an identical set of chromosomes. The last option relates to transcription, where genetic information is converted from DNA to mRNA, a process entirely separate from the events of mitosis.
