There are equal parts of guanine and cytosine, and adenine and thymine, because they form base pairs in the DNA molecule. This is in accordance with the base-pairing rule, which states that in DNA, adenine always pairs with thymine, and guanine always pairs with cytosine.
The nucleotide bases guanine and cytosine, and adenine and thymine are present in equal quantities in DNA. This is how scientists determined that guanine pairs with cytosine, and adenine pairs with thymine.
in each species the amount of adenine equals the amount of cytosine
According to Chargaff's rules, the percentage of adenine is equal to thymine in a double-stranded DNA molecule. These rules state that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.
There are four different nucleobases including adenine, thymine, guanine and cytosine. Each nucleobase pairs with it's opposite, for example adenine pairs with thymine and guanine pairs with cytosine. Knowing this, if a DNA sample had 10% thymine that means it would have 10% adenine equalling 20% of the entire sample for the both of them. The remaining 80% of the sample would contain 40% cytosine and 40% guanine.
Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.

There is no consistent amount of guanine in everyone's DNA, but there is an equal amount of guanine and cytosine as well equal amounts of thymine and adenine.
DNA contains four nucleic acid bases. These can be remembered by the acronym ACGT where the A stands for adenine, the C stands for cytosine, the G stands for guanine, and the T stands for thymine.

Based on the rule of complementary base pairing, the number (percentage) of adenine is equal to the number (percentage) of thymine, and the number (percentage) of cytosine is equal to the number (percentage) of guanine.
Yes because they always paired thymine with adenine or always paired adenine with thymine, never pairing either with cytosine or guanine. Therefore they are in equal amounts.

Chargaff's rule states that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine. This is because adenine forms complementary base pairs with thymine and cytosine with guanine, ensuring that DNA strands can bind together correctly.
If a species has 23% adenine, we know that adenine pairs with thymine. In DNA, the amount of adenine is equal to the amount of thymine, so together they make up 46% (23% adenine + 23% thymine). This leaves 54% for guanine and cytosine, of which guanine would be 27%.
There are four bases in the DNA double helix: adenine, guanine, cytosine and thymine. An adenine in one strand always pairs with a thymine in the other strand. Similarly, a cytosine always pairs with a guanine. So the number of adenines always equals the number of thymines, and the number of cytosines always equals the number of thymines. The total number of bases must equal 100%. So if 30% of the bases are adenine, another 30% must be thymine because they always pair with each other. Thymine and adenine added together therefore make 60% of the bases. The remaining 40% must be cytosine plus guanine. If the number of cytosines must equal the number of guanines, the percentage of cytosines must be ....... well, you can work it out for yourself!
