Nuclear DNA exists as complete of nucleoprotein called ...A.. that condenses into ...B.. during ...C... These A, B,C are respectively

Options

A. Chromatids , chromosomes,Interkinesis .
B. chromosomes Chromatids , S-phase.
C. Chromatin , Chromosome , Interphase .
D. Chromatin , Chromosome , M - phase .

Answer

To solve the question, we need to identify the terms A, B, and C that describe the relationship between nuclear DNA, its structure, and the phases of cell division.

1. **Understanding the Components**:
- **A**: We are looking for a term that describes the complete structure of nuclear DNA and proteins. This structure is known as **chromatin**. Chromatin consists of DNA wrapped around histone proteins.
- **B**: The next part of the question asks what chromatin condenses into. During cell division, chromatin condenses to form **chromosomes**. Chromosomes are the tightly packed structures that are visible during mitosis.
- **C**: Finally, we need to identify the phase during which this condensation occurs. The condensation of chromatin into chromosomes happens during the **M phase** (mitotic phase) of the cell cycle.

2. **Final Answer**:
- A = Chromatin
- B = Chromosome
- C = M phase

Thus, the complete answer is:
A: Chromatin, B: Chromosome, C: M phase.
