When a single bacterium undergoes binary fission, what is the result?

• A. Two genetically identical daughter cells
• B. Four genetically diverse cells
• C. One larger bacterium
• D. A spore and a vegetative cell

Answer: (A)

Verified step by step guidance

1. Understand the process of binary fission, which is the primary method of reproduction in bacteria.
2. Recall that during binary fission, a single bacterial cell duplicates its genetic material (DNA) and then divides into two parts.
3. Recognize that the division results in two cells that are genetically identical to the original parent cell because the DNA is copied exactly.
4. Eliminate options that suggest genetic diversity or unequal division, such as four genetically diverse cells or one larger bacterium.
5. Conclude that the correct result of binary fission is two genetically identical daughter cells.
