Similarity in DNA and RNA:
- Both are polymer of nucleotides
- Both have similar pyrimidine
- Both have similar sugar
- Both are genetic material
The Correct Option is A
Solution and Explanation
The similarity between DNA and RNA includes both being polymers of nucleotides and having similar sugar molecules (deoxyribose in DNA and ribose in RNA). They are both genetic material, but RNA is usually single-stranded and has uracil as a pyrimidine base instead of thymine, which is found in DNA.
So, the correct option is (A): Both are polymer of nucleotides

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Discovery of DNA
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)
