The correct answer is 2. 3:1
In the above diagram, red coloured DNA represents heavy DNA and green represents light DNA. The combination of two represents hybrid DNA. E .coli divides every 20 minutes. Therefore, the DNA extracted after 20 minutes had a hybrid density.
Proportions of light and hybrid densities DNA molecule after 80 mins= 6 light : 2 hybrid = 3 :1
