WebMar 5, 2024 · The pyrimidines, cytosine (C) and thymine (T), are smaller nitrogenous bases that have only a six-carbon ring structure. Figure \(\PageIndex{2}\): Nitrogenous bases within DNA are categorized into the two-ringed purines adenine and guanine and the single-ringed pyrimidines cytosine and thymine. Thymine is unique to DNA. WebTheoretical calculations and atomic force microscopy characterization of the adsorption of bases concluded that pyrimidines base loosely bind than the purine [5, 3, 12 ... adenine, cytosine and thymine were 6.27, 9.41, 6.90 and 7.53 kcal/mol (energy is -ve) respectively obtained at B3LYP/6-31G(d,p) level of theory.

WebMay 29, 2024 · The purines, adenine and thymine, are smaller two-ringed bases, while the pyrimidines, cytosine and uracil, are larger and have a single ring. What is another name for thymine? Thymine is also known as 5-methyluracil, ... Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. WebCorrect option is A) DNA and RNA are made up of nucleotides. They are of 2 types, purines and pyrimidines. Purines are 2 carbon - nitrogen-containing rings and pyrimidines are 3 carbon - nitrogen-containing cycle. Purines are adenine and guanine and pyrimidines are cytosine and thymines. So, option A " Cytosine and Thymine" is the correct answer. felix shop
