In cell division, the phase that starts with karyokinesis and ends with cytokinesis, is known as __________.

The correct answer is M phase.

Key Points

• The M phase, or mitotic phase, is where cell division occurs.
• The M phase includes both karyokinesis (division of the nucleus) and cytokinesis (division of the cytoplasm).
• Karyokinesis is the process of nuclear division, which is followed by cytokinesis.
• The M phase ensures that the two daughter cells receive an identical set of chromosomes.

Important Points

• The M phase is a crucial part of the cell cycle as it ensures genetic continuity through cell division.
• Proper regulation of the M phase is essential to prevent errors in chromosome segregation, which can lead to genetic disorders.

Additional Information

• Interphase
  • Interphase is the phase of the cell cycle during which the cell prepares for division.
  • It includes the G1, S, and G2 phases.
  • During interphase, the cell grows, replicates its DNA, and prepares for mitosis.
• G1 phase
  • The G1 phase is the first gap phase of interphase, where the cell grows and synthesizes proteins necessary for DNA replication.
• G2 phase
  • The G2 phase is the second gap phase of interphase, where the cell continues to grow and prepares for mitosis.
  • During this phase, the cell checks for DNA damage and repairs it if necessary.
