DNA - Discovery
Many individuals believe that American biologist - "James Watson" and English physicist - “Francis Crick” discovered DNA in the 1950s. Actually, this is not the case. Preferably, DNA was first recognized in the late 1860s by Swiss chemist - “Friedrich Miescher”.

What actually DNA is?
DNA is self-replicating material that exists in every living organism. In easiest terms, it is a carrier of all genetic information. It contains the instructions required for organisms to develop, grow, survive, and reproduce. It’s one of the longest molecules that contain our genetic “code,” or recipe. This recipe is the initial point for our development, but DNA’s interaction with outside impacts such as our lifestyle, environment, and nutrition ultimately forms human beings.
DNA is a composition of molecules known as nucleotides. Each nucleotide comprises a sugar and phosphate group, also nitrogen bases. These nitrogen bases are further tumbledown into four types, including:
- Adenine (A)
- Cytosine (C)
- Guanine (G)
- Thymine (T)
