Q. DNA was discovered by
Solution:
- Nucleic acids are organic molecules that carry genetic information in all living organisms. RNA is found in all living cells. In most plant viruses and few animal viruses, it is the genetic material. DNA is the genetic material for most of the living being except some viruses. This is because DNA is more stable due to its double-helical structure.
- Friedrich Meischer, a Swiss biochemist, was first to isolate nucleic acids from the nucleus of pus cells in 1869 and called it nuclein. Altman coined the term ‘Nucleic acid’ in 1889 due to the acidic nature of nuclein.
- Two kinds of nucleic acids are recognized in the living cells – DNA and RNA. DNA is found in all organisms except a few viruses. The greatest amount of DNA is concentrated in the nucleus. It also occurs in cell organelles like mitochondria, plastids and centrioles.
