In bacterial binary fission, as described in Figure 12.13 a , what is the primary role of actin-like molecules and associated proteins?

  • A: To form the mitotic spindle for chromosome separation.
  • B: To break down the nuclear envelope.
  • C: To anchor daughter chromosomes to specific sites on the plasma membrane and facilitate their movement to opposite ends of the cell.
  • D: To regulate the timing and rate of cell division.

Explanation

Figure 12.13 a states: 'The mechanism involves polymerization of actin-like molecules and possibly proteins that may anchor the daughter chromosomes to specific sites on the plasma membrane.' This anchoring helps in moving them to opposite ends of the cell during binary fission.
