Cytosine Thymine Adenine Guanine

Cytosine Thymine Adenine Guanine. In the case of DNA, those bases are adenine, guanine, cytosine, and thymine + This structure also shows the directionality of each of the two phosphate-deoxyribose backbones, or strands

One copy of the human genome consists of approximately 3 billion base pairs of DNA. Two hydrogen bonds are formed between adenine and thymine, but three hydrogen bonds hold together guanine and cytosine (Figure 2.127).

Adenine, thymine, cytosine and guanine are the four nucleotides found in DNA Note the similarity of the shapes of adenine and guanine, and also the similarity between cytosine and thymine A and G are classified as purines, while C and T are classified as pyrimidines

DNA structure. Base pairing and nucleotide. Cytosine, Thymine, Guanine, Adenine. Vector. The thymine (T) base on one strand can form two H-bonds with an adenine (A) base on the other strand (this is called an AT base pair). In the case of DNA, those bases are adenine, guanine, cytosine, and thymine

. The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine (credit a: modification of work by Jerome Walker, Dennis Myts) The Structure of RNA
