Statement Analysis: Mitosis vs. Meiosis
Evaluating the correctness of statements regarding cell division processes:
- Statement A: During mitosis, each nucleus divides once after DNA replication (Synthesis phase). This statement is correct, as mitosis involves one division cycle after DNA duplication.
- Statement B: DNA synthesis occurs before both mitosis and meiosis during interphase (S phase). While mitosis stages do not involve DNA synthesis, the statement asserts a specific synthesis percentage for meiosis. Accepting this premise for the question's context, statement B is considered correct.
- Statement C: In mitotic anaphase, sister chromatids separate, resulting in $2n$ chromosomes moving to each pole. In the anaphase II of meiosis, sister chromatids separate in haploid cells, leading to $n$ chromosomes moving to each pole. This statement is correct.
- Statement D: Crossing over is a characteristic event of meiosis (specifically Prophase I) and does not generally occur during mitosis. Thus, this statement is incorrect.
- Statement E: Crossing over is a fundamental process that occurs during meiosis. This statement is correct.

Based on the analysis, the correct statements are A, B, C, and E.
