Your teacher has given you a sample of soil to examine. Would you use a dry mount or a wet mount to examine it? Explain your reasoning.

Dry mount

Explanation:

Explanation:

As given here,

The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.

As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.

So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.
