MCQ
Which of the following is capable of self replication:
  • A
    A protein molecule
  • B
    A carbohydrate molecule
  • C
    A water molecule
  • A nucleic acid

Answer

Correct option: D.
A nucleic acid
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 $\text{DNA}$ and $\text{RNA.}$
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.
