Which one of the following will be untenable nucleotide combination?
1 Phosphate - deoxyribose - uracil
2 phosphate - ribose - uracil
3 phosphate - ribose - adenine
4 phosphate - deoxyribose - cytosine.
Explanation:
Exp: A Nucleotide comprises of nitrogen bases, pentose sugar, phosphate group. The nitrogenous base present in DNA are adenine, guanine, cytosine and thymine Deoxyribose sugar in DNA comprises thymine base whereas RNA comprises of uracil base.

Which is wrong about nucleic acids?
1 DNA is single stranded in some viruses.
2 RNA is double stranded occasionally.
3 Length of one helix is \(45 \AA\) in B-DNA.
4 One turn of Z-DNA has 12 bases.
Explanation:
Exp: C The double helical structure of DNA was given by Watson and Crick in 1953. The length of on helix in B-DNA is \(34 \AA\) i.e \(0.34 \mathrm{~nm}\) and the helical width is \(2 \mathrm{~nm}\). B-DNA is the most common form of DNA. It is a righthanded double helix, with 10 base pairs per turn. BDNA stabilized by the \(\mathrm{H}\)-bond between the nitrogenous bases of the two strands.

Flow cytometry allows detection of differences in length of nucleic acids as small as about:
1 \(1.5 \mathrm{Mbp}\)
2 \(15 \mathrm{Mbp}\)
3 \(25 \mathrm{Mbp}\)
4 \(100 \mathrm{Mbp}\)
Explanation:
Exp: A Flow cytometry allows detection of differences in length of nucleic acids as small as about 1.5 Mbp. Flow cytometry is a technology that rapidly analyzes single cells while suspended in diffused salt based solution.
