Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Unicellular organisms, such as bacteria, reproduce asexually through a process known as ____
A
Binary Fission
B
Conjugation
C
Meiosis
D
Mitosis
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: -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-3: -Unicellular organisms (like bacteria, yeast and archaea) typically grow using a method called binary fission. Here each single cell (mother cell) expands, replicates its genetic material, and divides into two cells (daughter cells).

Detailed explanation-4: -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.
