Question

In cell cycle, during interphase,

• A. Two daughter cells are produced.
• B. The nucleus is divided into two daughter nuclei.
• C. The chromosome condenses.
• D. The DNA is replicated.

Answer 1

The correct option is D The DNA is replicated.

The cell cycle is made up of two stages, interphase followed by mitosis. Mitosis is further divided into four phases, namely prophase, metaphase, anaphase and telophase followed by cytokinesis. Interphase is divided into G${}_1$ phase, S phase, G${}_2$ phase. At the end of the cell cycle during cytokinesis, two daughter cells are produced. At the end of mitosis during telophase, the nucleus is divided into two daughter nuclei and reaches two poles. At the start of mitosis during prophase, chromosome condenses. In interphase during S phase, the DNA is replicated.

Thus, the correct answer is option D.
