Chargaff's rule states that: A + G = T + C
Where A = Adenine, G = Guanine, C = Cytosine, and T = Thymine Also, G = C and A = T Some people discuss the G + C content of DNA. This refers to the amount of G + C relative to A + T. They use a simple variation of Chargaff's rule to show that: G + C
A + T If G + C is equal to A + T then the ration is 1. If there is a higher G + C content of the species, it will be greater than 1. If there is a lower G + C content of the species, it will be less than 1.

Is is true that hydrogen bonds can only form between adenine and cytosine?
No. Hydrogen bonds form between water molecules, adenine and thymine, adenine and uracil, guanine and cytosine, and a myriad of other molecules.
The number of hydrogen bonds between adenine and thymine in DNA is?
A double hydrogen bond binds adenine and thymine
Which nucleotides bonds with adenine?
Nucleotide, singular.Thymine binds with adenine.
How many hydrogen bonds do adenine and guanine have?
Uracil and Adenine do not form any bonds in making DNA.In DNA Adenine hydrogen bonds with Thymine (a double hydrogen bond). In RNA Uracil takes place of Thymine. Thus, Uracil and Adenine hydrogen bond in RNA. The base pairing is adjusted in RNA for this. Instead of A-T pairing that takes place in DNA, A-U pairing takes place in RNA.there are 2 hydrogen bonds between Adenine and Uracil (double bond).
Is adenine present in trna?
Yes.There are four bases in RNA. Adenine and guanine are purines (having two rings sharing one side); cytosine and uracil are pyrimidines (having a single ring).
Do hydrogen bonds only form between adenine and cytosine?
no, they form between adenine and thymine.
What did chargraff discover about the frequency of the nucleotides?
Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.
Is is true that hydrogen bonds can only form between adenine and cytosine?
No. Hydrogen bonds form between water molecules, adenine and thymine, adenine and uracil, guanine and cytosine, and a myriad of other molecules.
If thirty five percent thymine what percentages of each of the other bases are contained the same gene?
what is the ratio of Adenine to Thymine? What percent remains for Cytosine and Guanine? What is the ratio of Cytosine to Guanine?
Why all organism have same ratio of base pair in DNA?
Organisms normally have equal amounts of the bases adenine and thymine (ratio of A:T = 1) and equal amounts of the bases cytosine and guanine (ratio C:G = 1). The reason is that there is specific base pairing ie adenine can only pair with thymine and cytosine can only pair with guanine. So in a DNA double helix, every adenine in one strand must be paired with a thymine in the other strand. Similarly, every cytosine in one strand must be paired with a guanine in the other strand. Each base pair consists of a purine and a pyrimidine. Adenine and guanine are purines and thymine and cytosine are pyrimidines. This relationship between purines and pyrimidines was discovered by Erwin Chargaff in the 1950's. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/Chargaff%27s_rules
The number of hydrogen bonds between adenine and thymine in DNA is?
A double hydrogen bond binds adenine and thymine
How many hydrogen bonds are found between adenine and thymine?
2
What type of bound is found between adenine and thrmine?
hydrogen bond
How many adenine molecules are in ATP?
There are five carbon atoms in adenine.Its molecular formula is C5H5N5.For structural formulae, see the link below.
How do you determine the ratio between two sets of gears?
The ratio is the same as the ratio between the number of teeth.
What two bases are in purines?
Adenine and guanine are the two purines bases present in DNA.Two purines in DNA are adenine and guanine.
A ratio between mass and volume?
The ratio between mass and volume is density.
