alleryIn G2 of interphase, DNA content per cell relative to G1 is:
ADoubled (2C → 4C after S phase)
BSame
CTriple
DHalved
Answer & Solution
Correct answer: A. Doubled (2C → 4C after S phase)
**G1:** 2C (diploid, unreplicated).
**After S:** 4C (each chromosome has 2 chromatids).
**G2:** 4C (preparing for mitosis).
**After mitosis:** each daughter back to 2C.
*Note: chromosome NUMBER stays 2n in G1/G2/early M
only DNA amount changes.*
