NEET BIOLOGY

Detailed explanation-1: -Most bacteria rely on binary fission for propagation. Conceptually this is a simple process; a cell just needs to grow to twice its starting size and then split in two.

Detailed explanation-2: -In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA. Understand how pathogenic bacteria can cause botulism, typhoid, cholera, and pneumonia.

Detailed explanation-3: -Bacterial binary fission is the process that bacteria use to carry out cell division. Binary fission is similar in concept to the mitosis that happens in multicellular organisms (such as plants and animals), but its purpose is different.

Detailed explanation-4: -In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. This type of cell division is called binary fission.
