WebSep 29, 2024 · This layer is only 2 to 3 nm thick in Gram-negative bacteria. Shape: Gram-positive bacteria come in different shapes: cocci (spherical or round shape) bacilli (rod shape) WebIn this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell.
