Chemical analysis has shown that the number of adenine molecules in a sample of DNA is always the same as the number of thymine molecules. A sample of RNA would show that there are equal numbers of adenine molecules and uracil molecules.
Because thymine is the corresponding base to adenine. Therefor for every A on one side of the DNA strand, there is a T in the exact spot on the other arm of the strand.
yes.
Yes.
Thymine. Discovered in the late 1940s, this is known as "The Chargaff's Rules": DNA has equal numbers of adenine and thymine residues (A = T) and an equal number of guanine and cytosine (G = C). This was one of the most important features for Watson and Crick to solve the structure of DNA molecule in 1953.
There are three main section of a DNA molecule. The nitrogenous bases. Four in number. Guanine linked to cytosine and thymine linked to adenine. The deoxyribose sugar. The phosphate group backbone.
The genetic code is determined by the specific sequence of four nucleotide bases that make up DNA. The bases are guanine, adenine, thymine, and cytosine.
yes.
yes.
Chargaff's rules stated that the number of adenine units in a DNA segment were equal to the number of thymine units.
Yes, because the Adenine and Thymine pair with each other.
Yes, please.
Yes.
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!
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.
A double hydrogen bond binds adenine and thymine

C and G always are the same number. So since there are 45 cytosine, there has to be 45 guanine.Since there are 55 thymine, there has to be 55 adenine since those numbers are also the same.
