BIOXII06: MOLECULAR BASIS OF INHERITANCE
343166
In DNA, the complementary bases are:
1 Adenine and thymine; guanine and cytosine
2 Uracil and adenine; cytosine and guanine
3 Adenine and thymine; guanine and uracil
4 Adenine and guanine; thymine and cytosine
Explanation:
In DNA, guanine is the complementary base of cytosine, and adenine is the complementary base of thymine and of uracil in RNA.

As DNA is \(100 \mathrm{Kbp}\) long. The number of nucleotides, number of complete turns in the molecule and the length of the DNA molecule will be
(i) 100 kbp =100000 bp or 200000 base (ii) 10 bp forms 1 turn of DNA & there fore 100000 bp form 10000 turns. (iii) 10 bp are equal to 34A and therefore, 100000 bp are equal to \({\rm{3}}{\rm{.4 \times 1}}{{\rm{0}}^{\rm{4}}}\;{\rm{nm}}\;{\rm{or}}\;{\rm{3}}{\rm{.4 \times 1}}{{\rm{0}}^{\rm{5}}}\;{\rm{A}}\;{\rm{or}}\;{\rm{3}}{\rm{.4 \times 1}}{{\rm{0}}^{{\rm{ - 5}}}}\)

In 1953 James Watson and Francis Crick, gave the double helical model of DNA based on the
1 X-ray refraction data produced by Maurice Wilkins and Rosalind Franklin
2 X-ray diffraction data produced by Maurice Wilkins only
3 X-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin
4 X-ray diffraction data produced by Chargaff and Rosalind Franklin
Explanation:
In 1953 that James Watson and Francis Crick, based on the X-ray difdfraction data produced by Maurice Wilkins and Rosalind Franklin.
