Explanation:
Miescher discovered nucleic acids from pus cells in discarded surgical bands.
He observed that these were acidic in nature.
The two types of nucleic acid were DNA and RNA.
These are considered as the hereditary unit of the cell.
These carry characters from one generation to the other.
A nucleic acid molecule can act as genetic material because nucleic acids possess the ability of self-replication, i.e., capacity to generate their own copies.
