Watson and Crick first built a triple-helix model of DNA. In this model, the nitrogenous bases were on the outside of the DNA mo
Sedaia [141]

Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

<h3>What is DNA molecule?</h3>
  • Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
  • Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
  • An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
  • To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.
