Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
Because there are trillions of different arrangements of genes in those long chains.
Because the bases can be arranged in many different combinations

LUCA
Last Universal Common Ancestor of all life on earth.
somewhere around 5 to 30 million
The National Science Foundation's "Tree of Life" project estimates that there could be anywhere from 5 million to 100 million species on the planet, but science has only identified about 2 million.
Approximately 3 million years ago in a bacterial cell.
Amount of Unicellular and Multicellular OrganismsMore than 1 and 1|2 (one half) million kinds of organisms have been identified. That number is small compared to the estimated number of unicellular organisms that exist and have not been identified. Scientists estimate that there are more than 1 billion kinds of unicellular organisms!
Yes, thoroughly, however it takes two to three Billion Years to Explain it All. For example, all the while minor Organisms where in Full Living Swing, the Parting of the minor Organisms into The Two Sexes occurred 575 Million Years Ago.
Because the bases can be arranged in many different combinations (Apex)
The power of polymerization and the law of large numbers.
Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
They can't be arranged in a million different ways!
Organisms first got a nucleus about 460 million years ago.
One line of thinking would be that this is evidence of the eventual divergence of all living things from the same original primitive life forms.
The Truman Doctrine
The first winged organisms were insects which evolved wings about 350 million years ago.
