Question

In order to prevent the DNA from breaking, the glass rod should be spun
A) True
B) False

Answer 1

Spinning the glass rod is true to prevent DNA from breaking.

Step-by-step explanation:

The statement is True.

When the DNA is precipitated with ethanol and forms viscous strands, it is important to prevent the DNA from breaking. Spinning the glass rod can help prevent the DNA from breaking. The centrifugal force generated by spinning the glass rod helps to keep the DNA strands intact.

For example, imagine holding a wet towel. If you spin it, the centrifugal force prevents the individual threads of the towel from breaking apart. Similarly, spinning the glass rod helps to keep the DNA strands from breaking.
