What is the cell cycle?

• When cells arrange themselves in a circle

• When duplication of RNA and lipids occur to produce more cells in a systematic manner

• A series of events that take place to duplicate DNA and produce daughter cells

• A series of events that take place to duplicate genes and produce daughter cells

What happens in Interphase?

• The cells are at rest before the active division phase starts

• The cells are producing more nuclei

• The cells are synthesizing DNA, RNA, and proteins

• The cells all go into G0 phase and withdraw from the cell cycle

Which of these cannot be attributed to Prophase?

• Chromosomes get duplicated

• Nucleus and nucleolus disappear

• Centrioles occupy opposite poles of the cell

• Spindle fibers appear

• Chromosomes get attached to the spindle fibers via centromere
