15 Questions
What is the sequence of events by which a cell duplicates its genome, synthesises the other constituents of the cell, and eventually divides into two daughter cells termed?
Cell cycle
In the context of cell division, what are the three processes that have to take place in a coordinated way to ensure correct division and formation of progeny cells containing intact genomes?
Cell division, DNA replication, and cell growth
What are the characteristics of cells that are shared by all living organisms according to the given text?
Growth and reproduction
What is the significance of meiosis in the context of cell division?
Introduction of genetic variation
What is the process by which all cells reproduce by dividing into two, with each parental cell giving rise to two daughter cells each time they divide?
Asexual reproduction
What must take place in a coordinated way during the division of a cell to ensure correct division and formation of progeny cells containing intact genomes?
DNA replication, cell division, and cell growth
During which phase of the cell cycle does DNA replication occur?
S phase
What is the duration of the average cell cycle of human cells in culture, as mentioned in the text?
24 hours
What is the main function of G1 phase in the cell cycle?
Cell growth without DNA replication
What occurs during the G2 phase of the cell cycle?
Protein synthesis in preparation for mitosis
What represents the phase when the actual cell division or mitosis occurs?
M Phase
What is the significance of the interphase in the cell cycle?
Preparation for division by undergoing both cell growth and DNA replication
What occurs during the S or Synthesis phase of the cell cycle?
DNA synthesis or replication takes place, doubling the amount of DNA per cell
Which phase corresponds to the interval between mitosis and initiation of DNA replication?
G1 phase (Gap 1)
What marks the period during which DNA synthesis or replication takes place?
S phase (Synthesis)
