Select the incorrect statement for the given figure.

Options

  1. AA polymer thus formed has at one end a free phosphate moiety at 5' -end of sugar, which is referred to as the
  2. BSimilarly, at the other end of the polymer the sugar has a free OH of 3'C group which is referred to as the 3'
  3. CThe backbone of a polynucleotide chain is formed due to sugar and nitrogenous bases.
  4. DThe nitrogenous bases linked to the sugar moiety project from the backbone.

Correct answer

C. The backbone of a polynucleotide chain is formed due to sugar and nitrogenous bases.

Step-by-step solution

A polymer thus formed has at one end a free phosphate moiety at 5' -end of sugar, which is referred to as 5’-end of polynucleotide chain. Similarly, at the other end of the polymer the sugar has a free OH of 3'C group which is referred to as 3' -end of the polynucleotide chain.
