(a)
Interpretation:
The DNA double helix with reference to the sugar-phosphate backbone should be described in detail.
Concept Introduction:
The modern structure of DNA was proposed by James Watson and Francis Crick. DNA has two polynucleotide strands parallel to each other and in opposite direction and has wind up into a right handed double helix.

- How many chiral carbons are in the molecule? OH F CI Brarrow_forwardA mixture of three compounds Phen-A, Acet-B and Rin-C was analyzed using TLC with 1:9 ethanol: hexane as the mobile phase. The TLC plate showed three spots of R, 0.1 and 0.2 and 0.3. Which of the three compounds (Phen-A; Acet-B or Rin-C) would have the highest (Blank 1), middle (Blank 2) and lowest (Blank 3) spot respectively? 0 CH: 0 CH, 0 H.C OH H.CN OH Acet-B Rin-C phen-A A A <arrow_forwardHow many chiral carbons are in the molecule?
