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.
