    Question: What is the primary method of multiplication (reproduction) in bacteria?

    Options:

    Binary fission
    Budding
    Fragmentation
    Parasexually

    -✅Explanation: Binary fission is the primary method of reproduction in bacteria. In this process, a single bacterial cell divides into two identical daughter cells. The bacterial chromosome is duplicated, and the cell splits into two, each containing a copy of the original genetic material. The steps are:
    -DNA replication: The bacterium duplicates its genetic material.
    -Cell elongation: The cell grows larger.
    -Cell division: The cell divides into two identical daughter cells.

    📌Other Options Explanations:
    -Budding: Some bacteria can reproduce by budding (forming a smaller outgrowth that separates).
    -Fragmentation: Certain filamentous bacteria reproduce by breaking into smaller units.
    -Parasexual: Refers to genetic recombination mechanisms in bacteria.

    🛑 Additional Information::::
    -Binary Fission:-​
    -It is a kind of asexual reproduction in which the organism divides itself in two.
    -It occurs in some single-celled Eukaryotes like the Amoeba and the Paramoecium.
    -In binary fission, the fully grown parent cell splits into two halves, producing two pools.
    -After replicating its genetic material, the parent cell divides into two equal sized daughter cells.
    -The daughter cells are genetically identical.
