What is binary fission?

Binary fission is defined as a method of asexual reproduction that occurs in certain prokaryotic organisms, such as bacteria. In this process, a single cell replicates its genetic material and divides into two identical daughter cells. Each of these new cells contains an exact copy of the original cell's DNA, ensuring genetic consistency. This method is efficient for organisms that need to reproduce quickly and in large numbers, allowing for rapid population growth under favorable conditions.

Understanding binary fission is crucial in microbiology and in the study of various organisms, as it illustrates one of the primary ways that prokaryotes reproduce and proliferate. This process stands in contrast to sexual reproduction, which involves the combination of genetic material from two parents, forming offspring that are genetically distinct. In binary fission, the offspring are clones of the parent cell, highlighting the simplicity and efficiency of this form of reproduction.

The other options distinctly depict different biological processes, clarifying the specific nature of binary fission among a diversity of cellular functions and reproductive strategies.
