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.

<h3>What is phylogenetic tree?</h3>
A phylogenetic tree simply refers to a branching diagram or a tree showing the evolutionary relationships among various biological species of both plants and animals based on their similarities and differences; either genetically or physically
Generally, animals; be it vertebrates or invertebrates has the few characteristics below:
- All animals are multicellular organisms
- Animals are also heterotrophic, meaning; they depend on other organisms for food or they obtain their energy by consuming energy-releasing food substances.
- Animals typically reproduce sexually.
- All animals are also made up of cells that do not have cell walls.
In conclusion, the phylogenetic tree of organisms within the animal kingdom include all characteristics mentioned above
