NEET BIOLOGY

Detailed explanation-1: -binary fission, asexual reproduction by a separation of the body into two new bodies. 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.

Detailed explanation-2: -Bacterial binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes. In both cases, chromosomes are copied and separated, and the cell divides its cytoplasm to form two new cells.

Detailed explanation-3: -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-4: -Fission is a kind of Asexual reproduction. It refers to the process of producing new offspring from a single parent. Both physically and genetically, the offsprings are identical to one another. They are identical to their parent cell. As a result, they are ‘clones’.

Detailed explanation-5: -Bacteria replicate by binary fission, a process by which one bacterium splits into two. Therefore, bacteria increase their numbers by geometric progression whereby their population doubles every generation time. Generation time is the time it takes for a population of bacteria to double in number.
