Upon examination, a cell is found to have twice as much DNA as the normal diploid state but is no longer in the process of replicating the DNA. All of the DNA is found within a single nucleus. Which stage of the cell cycle is this cell in?
A. M phase
B. S phase
C. G1 phase
D. G2 phase
E. cytokinesis

D. G2 phase

Explanation:

The G2 phase is last phase or stage that occurs in the metabolic phase of a cell cycle also know as the Interphase.

The G2 phase is referred to as the cell division phase in a cell cycle. It is a phase whereby twice as much DNA as the normal diploid state is found in the cell but is no longer in the process of replicating the DNA and all of the DNA is found within a single nucleus.

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
