Well, as you should know, the A and T gene are interjoined as well as the C with G gene.
The A and T genes in DNA are mostly resposible for the physical appearance (colour, shape) of an organism. The C and G genes are resposible for an organism's interior (eyesight, smell sense, diseases).
So in this case, with 24% A and 34% T, we can clarify that the organism was defected, as their was an unequality amongst them two, which could mean that their was a lack of A genes.
23% C and 19% G wold not matter greatly as their is not a large difference amonsgt the two and this could have been a simple analytical error.

It's because of two reasons. The first is because of the fact that the number of nucleotides in DNA are always present in a characteristic ratio, and are not equal to each other. This shows that DNA has molecular diversity, which means that it is a better candidate for the genetic material than a protein is. It was one of the first steps to the discovery that DNA is the reason for heredity.
The second reason is because adenine and thymine base-pair with each other, and cytosine and guanine base pair with each other also. That's why the percentages of A to T and of C to G are similar. This is known as Chargaff's rules, named after Erwin Chargaff who discovered it, and proves that A and T base pair with each other, and that C and G base pair with each other.

If you add the numbers up you get 100%.
They are just the percentages of the four different amino acids that make up DNA.
No mystery there.

Maybe it is single stranded, then you would not expect a equal ratio of A with T and G with C. But, this is not my field.
