adenine In a DNA strand, the amount of Adenine equals the amount of Thymine, and the amount of Guanine equals the amount of Cytosine. So Adenine is your answer.
Those are Chargraff's Rules. You're wrong to think that adenine and thymine are the only pairs however because in RNA, adenine always pairs with uracil. Thymine is not in RNA. Adenine and Guanine are purines. Cytosine, thymine, and uracil are purimidines. Sources: My Science class and textbook Hope this helped!
Short answer: Adenine More information: In the model of DNA that was discovered by Rosalind Franklin, James Watson and Francis Crick in 1953 proposed that DNA was a double helix structure with 4 bases which pair to each other. Due to experiments that had been carried out by other scientists at the time (namely Erwin Chargoff in 1949) he showed that despite the amount of DNA present the amount of adenine was always equal to the amount of thymine and the amount of cytosine to the amount of guanine. When Watson had this information he suddenly realised that the adenine-thymine bond was the same length as the cytosine-guanine bond and therefore they would pair to each other in a double helix model. Thymine and adenine are held together by a double hydrogen bond; whereas cytosine and guanine form a triple hydrogen bond.
Chargaff's rules state that in DNA, the amount of adenine (A) is equal to the amount of thymine (T). This is known as complementary base pairing, where A always pairs with T in the double helix structure of DNA.
Yes, in a sample of DNA, the amount of adenine is equal to the amount of thymine due to the complementary base pairing rule where adenine pairs with thymine. This relationship is known as Chargaff's rules.

Erwin Chargaff discovered that the bases of DNA (adenine, thymine, cytosine, and guanine) attach to the deoxyribose sugars. Chargaff's rules state that in DNA, the amount of adenine always equals the amount of thymine, and the amount of cytosine always equals the amount of guanine.

According to Chargaff's rules, the amount of adenine always equals the amount of thymine in a DNA molecule. Similarly, the amount of guanine always equals the amount of cytosine. This principle is fundamental to the structure of DNA and base pairing.
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.
Cytosine is a nitrogen bases that is found in the DNA. There is four nitrogen bases and this is one of them. The amount of cytosine in cells always equals the amount of guanine, and the amount of adenine always equals the amount of thymine.
Erwin Chargaff discovered that the amount of adenine in DNA always equaled the amount of thymine. This observation is part of his rules, which state that in double-stranded DNA, the amount of guanine equals that of cytosine as well, highlighting the base pairing relationships crucial for the structure of DNA.
