NEET BIOLOGY

Detailed explanation-1: -The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.

Detailed explanation-2: -Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus.

Detailed explanation-3: -Mitosis is required for the growth, repair, and regeneration of dead and damaged cells. Mitosis produces genetically and morphologically identical cells. Asexual reproduction in eukaryotic organisms involves mitosis.

Detailed explanation-4: -Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

Detailed explanation-5: -Meiosis, in contrast, is a specialized kind of cell cycle that reduces the chromosome number by half, resulting in the production of haploid daughter cells. Unicellular eukaryotes, such as yeasts, can undergo meiosis as well as reproducing by mitosis.
