What happens during the G1 phase of interphase?
During the G1 phase, the cell performs its normal functions, grows, and produces organelles, enzymes, and proteins.
What is synthesized during the S phase of interphase?
During the S phase, DNA is synthesized or replicated, producing replicated chromosomes with two sister chromatids.
What additional structure is replicated during the S phase besides DNA?
The centrosome, a cytoplasmic protein important for mitosis, is also replicated during the S phase.
What characterizes the G2 phase of interphase?
The G2 phase is characterized by continued cell growth and preparation for the M phase, including the production of new proteins required for cell division.
What is the G0 phase in the cell cycle?
The G0 phase is a non-dividing phase where cells do not continue through the cell cycle and can remain temporarily or permanently.
What is the main event that occurs during the M phase of the cell cycle?
The M phase involves cell division, which occurs relatively quickly compared to interphase.
