18 Questions
What is the significance of the G0 phase in the cell cycle?
It is a phase where cells do not divide or copy themselves
Why does interphase precede mitosis in the cell cycle?
It duplicates the DNA and prepares the cell for division
In mitosis, what is the role of the centrosome during cell division?
Organize microtubules and form the spindle for chromosome division

Which phase of the cell cycle involves the synthesis of new DNA molecules?
S Phase
How does mitosis contribute to maintaining the chromosome number in each generation?
By equally dividing chromosomes through spindle formation
