Question

Match the cell cycle phase with the events:

_____________________

G2

      [ Choose ]            Increase in overall cell size.            Replenish cell's energy stores.            Sister chromatids are pulled apart.            DNA is duplicated to produce identical sister chromatids.      

G1

      [ Choose ]            Increase in overall cell size.            Replenish cell's energy stores.            Sister chromatids are pulled apart.            DNA is duplicated to produce identical sister chromatids.      

S Phase

      [ Choose ]            Increase in overall cell size.            Replenish cell's energy stores.            Sister chromatids are pulled apart.            DNA is duplicated to produce identical sister chromatids.      

M Phase

      [ Choose ]            Increase in overall cell size.            Replenish cell's energy stores.            Sister chromatids are pulled apart.            DNA is duplicated to produce identical sister chromatids.      

In eukaryotic organisms, cell division is used for growth and development as well as the production of replacement cells. There are times when new cells are not needed. If a cell is not actively dividing or getting ready to divide, what phase/stage would it be in?

Explanation / Answer

(1)

S Phase: DNA is duplicated to produce identical sister chromatids

G1 Phase: Increase in overall cell size.             

G2 Phase:Replenish cell’s energy stores.            

M Phase: Sister chromatids are pulled apart.             

(2)

Answer:

The G0 phase is a period in the cell cycle in which cells exist in a quiescent state.
