<span>Two of the nitrogenous bases present in DNA (Guanine and Adenine) contain two rings and thus are much larger than the other two (Cytosine and Thymine), which have only one.
Nitrogenous bases with two rings (such as G and A) are known as PURINES, whereas nitrogenous bases with a single ring (such as C and T) are known as PYRIMIDINES.
A stable DNA structure is formed ONLY when the two strands are a constant distance
apart which ONLY happens when a PURINE (G or A) on one strand is paired with a PYRIMIDINE (C or T) on the other strand. The strands would have to move much further apart to permit a purine to pair with another purine and would have to move much closer together to permit a pyrimidine to pair with a pyrimidine.

I will give you a website that has a chart on it
The characteristics that makes golden eagles successful hunters is their good eyesight and their large wingspans.
<h3>The characteristics of a golden eagle:</h3>
The golden eagle is one of the most widespread eagle in the world.
That is because they are able to adapt in almost every type of climate, especially open areas with vegetation.
Some of the characteristics that makes them successful hunters is the good eyesight and large wingspans they possess.
Taking the vision of human beings for example, what looks sharp and clear to us at 5 feet is just as clear to a golden eagle from 20 feet away.
Also, their large wingspans helps then fly long distance in search of preys.
Therefore, the characteristics that makes golden eagles successful hunters is their good eyesight and their large wingspans.
