2 rings each .
Adenine and guanine molecules are two of the four nitrogenous bases that help make up the structure of DNA. They are also known as "purine" bases because they have a double ring structure. The purine bases are extremely important in DNA formation and they specifically pair up with the other two nitrogenous bases, known as the "pyrimidine" bases. Adenine molecules will always pair with thymine molecules and guanine molecules will always pair with cytosine.
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
Four different ribonucleotides are present in RNA. They are Uracil, Adenine, Guanine and Cytosine.
4. adenine,thymine, guanine ,cytosine
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.
4. adenine,thymine, guanine ,cytosine
There are only 4 nitrogenous bases in DNA. These are adenine, thymine, guanine, and cytosine. Adenine will only pair with thymine, and guanine will only pair with cytosine.
There are four different nitrogen bases found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). These nitrogen bases are the building blocks that make up the genetic code of an organism.
There are 4 bases in DNA: adenine, thymine, cytosine, and guanine.
There are four bases in DNA; adenine, thymine, cytosine, and guanine and in the rare case Uracil can also exist in the DNA. But Uracil DNA glycocylase normally cut it and helps to replace T base by DNA polymerase. But when there is low ration of T over U, DNA polymerase never mind to add U in place of T. This will inturn activates a specific mode of cell death due to hyper Us.
Four: Adenine, Thymine, Cytosine, and Guanine; commonly abbreviated to A, T, C, and G.
Bacterial DNA has four nitrogen bases; adenine, guanine, cytosine, and thymine.
