WebMay 2, 2024 · cytosine and guanine How is DNA paired? DNA is the biological molecule that stores genetic information in living cells. DNA molecule is made up of monomers called nucleotides. These nucleotides are four in number and are as follows: Adenine Thymine Cytosine Guanine The statement that correctly pairs DNA bases are as follows: … WebMay 14, 2024 · C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) This is consistent with there not being enough space (20 Å) for two purines to fit within the helix and too much space for two pyrimidines to get close enough to each other to form hydrogen bonds between them. But why not A with C and G with T?

WebThe DNA molecule is a polymer of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines … Webcytosine: [noun] a pyrimidine base C4H5N3O that codes genetic information in the polynucleotide chain of DNA or RNA — compare adenine, guanine, thymine, uracil.
WebJun 14, 2024 · The nitrogenous bases adenine (A) and guanine (G) are the purines; they have a double-ring structure with a six-carbon ring fused to a five-carbon ring. The pyrimidines, cytosine (C) and thymine (T), are smaller nitrogenous bases that have only a six-carbon ring structure. WebJul 12, 2024 · Researchers have long been intrigued by the possibility that evolution could have gone in a different direction with DNA’s four bases: adenine (A), thymine (T), cytosine (C) and guanine (G).
