CELL DIVISION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The method of reproduction used by prokaryotic organisms (bacteria), in which the organism divides into two genetically identical organisms is called
A
conjugation
B
meiosis
C
sexual reproduction
D
binary fission
Explanation: 

Detailed explanation-1: -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. Binary fission is the primary method of reproduction of prokaryotic organisms.

Detailed explanation-2: -How do prokaryotes reproduce? Prokaryotes reproduce through a cell division process called binary fission. Like mitosis in eukaryotes, this process involves copying the chromosome and separating one cell into two.

Detailed explanation-3: -What is binary fission? 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: -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-5: -Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm.
