Identify the incorrectly matched pair in the given options.

Options

  1. ADNA duplication - S-phase
  2. BReductional division - Meiosis
  3. CEquational division - Mitosis
  4. DCrossing over - Sister chromatids of homologous chromosomes.

Correct answer

D. Crossing over - Sister chromatids of homologous chromosomes.

Step-by-step solution

In the cell cycle process, S phase is a part of the interphase stage. In this phase, the DNA of the cell is duplicated marking the decision of the cell to enter divisional stage. Mitosis is one of the two cell-division processes where the outcome is two daughter cells who are identical to the parent cell. Since new cells formed as equal/same in every aspect, this division is also called as equational division. Meiosis is the other type of division where the daughter cells formed have half the genetic content of the
