KROK 1 2008 – Question 124 · KROK (Medicine) · Biology
Life cycle of a cell includes the process of DNA autoreduplication. As a result of it monochromatid chromosomes turn into bichromatid ones. What period of cell cycle does this phenomenon fall into?
- A. S
- B. G2
- C. G1
- D. M
- E. G0
Hint
Chromosomes become bichromatid only when DNA is copied. Compare the DNA content (2c versus 4c) before and after the event in the stem and decide which stage of interphase this belongs to.
