Question

The cellular structure which disappear during mitosis is

• A. Plasma membrane
• B. Nuclear membrane
• C. Mitochondria
• D. Nuclear membrane and nucleolus

Answer 1

The correct option is D Nuclear membrane and nucleolus

The cellular structure that disappears during mitosis is nuclear membrane and nucleolus. Mitosis maintains genetic similarity. The sequence of events is divided into stages corresponding to the completion of one set of activities and the start of the next. These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the chromosomes, which have already duplicated, condense and attach to fibers that pull one copy of each chromosome to opposite sides of the cell. The cell then divides by cytokinesis to produce two genetically identical daughter cells.

So, the correct answer is 'Nuclear membrane and nucleolus'.
