Adenine is \(30 \%\). What would be percentage of guanine?
1 \(10 \%\)
2 \(20 \%\)
3 \(30 \%\)
4 \(40 \%\)
Explanation:
If adenine \(=30 \%\) as adenine will always pair with thymine, i.e., thymine is also \(30 \%\). Then guanine and cytosine accounts \(40 \%\) as guanine will always pair with cytosine. So Adenine \(=30 \% \quad\) Thymine \(=30 \%\) Guanine \(=20 \% \quad\) Cytosine \(=20 \%\) OR Adenine \(=30 \%\) \(\mathrm{A}+\mathrm{G}+\mathrm{C}+\mathrm{T}=100 \%\) \(30 \%+\mathrm{G}+\mathrm{C}+30 \%=100 \%\) \(\mathrm{G}+\mathrm{C}+60 \%=100 \%\) \(\mathrm{G}+\mathrm{C}=100 \%-60 \%\) \(\mathrm{G}+\mathrm{C}=40 \%\) \({\rm{G/C = 40\% /2}}\) Hence, \(\mathrm{G}=20 \%\)

In some viruses, DNA is synthesised by using RNA as template. Such a DNA is called:
1 A-DNA
2 B-DNA
3 cDNA
4 rDNA
Explanation:
Complementary DNA (cDNA) is double -stranded DNA synthesized from a messenger RNA (mRNA) template in a reaction catalysed by the enzyme reverse transcriptase.

The two polynucleotide chains in DNA are
1 Discontinous
2 Antiparallel
3 Semi-conservative
4 Parallel
Explanation:
The two chains of DNA have anti-parallel polarity. It means, if one chain has the polarity 5'à3', the other has 3'à5'
