In DNA adenine pairs with?
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.
What two base pairs would not be found in a cell?
Cytosine and adenine do not pair with each other in DNA. Instead, cytosine pairs with guanine, while adenine pairs with thymine.
What is correct about Chargaff's rule for each species A adenine equals guanine B adenine equals thymine C adenine equals cytosine D adenine guanine thymine and cytosine amounts are equal?
in each species the amount of adenine equals the amount of cytosine
What is a nucleotide that pairs with guanine?
In DNA, nucleotide cytosine and guanine pairs with each other. Nucleotide adenine and thymine also pairs with each other. However in RNA, the thymine is not present, so in its place, uracil pairs with adenine.
What bonds Adenine and Thymine together?
The Watson-Crick base pair of Thymine is Adenine. The two molecules are bound together by a set of three hydrogen bonds. Thymine can also form what are known as Thymine dimers when exposed to UV radiation, which is the source of damage to DNA from overexposure to UV radiation and can cause cancer.

What are the two nitrogen bases from DNA that link together?
Guanine and Cytosine pair with each other and Adenine and Thymine pair with each other.
How many molecules of adenine and thymine are in each DNA model?
In DNA, adenine always pairs with thymine. Therefore, in each DNA model, the number of adenine molecules will be equal to the number of thymine molecules. The exact count of adenines and thymines will depend on the length of the DNA strand in the model.
What bonds Adenine and Thymine together?
The Watson-Crick base pair of Thymine is Adenine. The two molecules are bound together by a set of three hydrogen bonds. Thymine can also form what are known as Thymine dimers when exposed to UV radiation, which is the source of damage to DNA from overexposure to UV radiation and can cause cancer.
If thirty five percent thymine what percentages of each of the other bases are contained the same gene?
If 35% of the gene is thymine, then you know that adenine will also be 35%, as they pair together. Similarly, guanine will be 15% and cytosine will be 15% to complement their pairing percentages with adenine and thymine.
What are the nitrogen based pairs?
The nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. They pair with each other as follows: adenine pairs with thymine, and cytosine pairs with guanine. The nitrogen bases in RNA are adenine, guanine, cytosine, and uracil. They pair with each other as follows: adenine pairs with uracil, and cytosine pairs with guanine.
Are there always going to be an equal number of adenine and thymine nucleotides in a molecule why?
Yes, there will always be an equal number of adenine (A) and thymine (T) nucleotides in a DNA molecule. This is because adenine always pairs with thymine through hydrogen bonding in a double-stranded DNA molecule, following Chargaff's rule.
What nucleotide replaces thymine?
Uracil replaces Thymine in DNA. Adenine and Thymine go together while Cytosine and Guanine go with each other in DNA. But, in RNA, Thymine is replaces with Uracil. So not Adenine and Uracil go together, while Cytosine and Guanine pair up.
What scientist found that DNA contains equal amount of thymine and adenine?
Erwin Chargaff is his name
