Which of the following scientists demonstrated that in DNA, \(\mathrm{A}=\mathrm{T}\) and \(\mathrm{G}=\mathrm{C}\) ?
1 Frederick Griffith
2 Meselson and Stahl
3 Hershey and Chase
4 Erwin Chargaff
Explanation:
Austrian chemist Erwin Chargaff stated that DNA of any cell must have a 1:1 ratio of pyrimidine and purine bases and, particularly the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. This pattern is seen in both strands of the DNA.

Purines in RNA are
1 Thymine and cytosine
2 Thymine and uracil
3 Adenine and guanine
4 Uracil and cytosine
Explanation:
Purines - Adenine and guanine are two of the five bases in nucleic acids. The complement of adenine is uracil instead of thymine, in RNA.

The backbone of DNA double helix consists of:
1 Sugar-Base
2 Hydrogen bond
3 Sugar-Phosphate
4 Nitrogen base
Explanation:
The backbone of a polynucleotide chain is formed due to sugar and phosphates.
