WebBacterial DNA is 1000 times longer than the cell that contains it. The DNA must be supercoiled in order to fit into the cell. The length of the single DNA molecule needed to carry the 4000 or so genes of a bacterial cell is about 1.5 mm, and this structure is compacted into 0.2 μm 3!Thus, a stretched out bacterial chromosome is a thousand … WebDNA carries genetic material in Streptococcus bacteria & used DNase, RNase, and protease to try and identify the genetic material. Griffiths (1928) mixed heat-killed 'S' bacteria with 'R' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 'S' bacteria from the dead mouse.
