What is the function of ribonuclease in DNA purification process?
Options
- ATo remove proteins from DNA
- BTo remove RNA from DNA
- CTo remove lipids from DNA
- DTo remove polysaccharides from DNA
Correct answer
B. To remove RNA from DNA
Step-by-step solution
The RNA can be removed by treatment with ribonuclease whereas proteins can be removed by treatment with protease. Other molecules can be removed by appropriate treatments and purified DNA ultimately precipitates out after the addition of chilled ethanol. This can be seen as collection of fine threads in the suspension
