d. DNA is insoluble in alcohol.
Adding alcohol (isopropanol) to a DNA solution helps to precipitate or separate the DNA from other cellular components. DNA is not soluble in alcohol, so when alcohol is added, it causes the DNA to separate and form visible strands or clumps, which can then be collected and isolated.
Why was it necessary to add alcohol (isopropanol) to precipitate DNA? This is because:
a.
The alcohol sterilizes the DNA.
b.
The alcohol dissolves the cell membranes.
c.
DNA is insoluble in water.
d.
DNA is insoluble in alcohol.
