Binary Fission Quiz

What is the primary purpose of binary fission in bacterial cells?

• To ensure genetic identity between parent and daughter cells

• To increase the size of the bacterial cell

• To eliminate harmful mutations

• To create genetically diverse offspring

How does binary fission differ from mitosis?

• Binary fission results in genetically diverse cells

• Binary fission is simpler and occurs in prokaryotic cells

• Binary fission occurs in eukaryotic cells

• Binary fission is more complex than mitosis

What type of chromosome do bacterial cells possess?

• Linear chromosomes

• Multiple circular chromosomes

• A single circular chromosome

• No chromosomes

What is the first step in the binary fission process?

• Chromosome replication

• Cell division

• Cell membrane growth

• Chromosome attachment to the membrane

How do replicated chromosomes move apart during binary fission?

• They are pushed apart by spindle fibers

• They are pulled apart by the growing cell membrane

• They are separated by a contractile ring

• They move apart due to cytoplasmic streaming

What happens to the cell membrane during the final stages of binary fission?

• It dissolves completely

• It cleaves to form two separate cells

• It forms a new nucleus

• It merges with another cell

What ensures that the daughter cells are genetically identical to the parent cell?

• Random mutation

• Accurate DNA replication and distribution

• Environmental factors

• Selective gene expression

What is the result of the binary fission process?

• Two genetically identical daughter cells

• One larger cell

• Four genetically identical cells

• Two genetically diverse cells

Which phase in mitosis is similar to the final stage of binary fission?

• Anaphase

• Prophase

• Metaphase

• Telophase

What is the significance of the cell membrane's role in binary fission?

• It initiates DNA replication

• It ensures the separation of chromosomes

• It prevents cell division

• It provides energy for the process
