Molecular Formula: C4H5N3O: Molecular Weight: 111.104 g/mol: InChI Key: OPTASPLRGRRNAP-UHFFFAOYSA-N: LogP-1.73: Synonyms: Cytosine; 4-Aminopyrimidin-2(1H)-one; 2(1H)-Pyrimidinone, 4-amino-71-30-7; . As mentioned before, each base is classified as either a purine (two-ring molecule) or a pyrimidine (one-ring molecule), as follows: According to Chargaff's rules, a purine base can only pair with a pyrimidine base, and vice versa. The phosphate group of one nucleotide connects via a phosphodiester bond to the sugar of the adjacent nucleotide &mdash, which connects by a phosphodiester bond to its neighbor; this makes up the sugar-phosphate backbone of the DNA molecules, which is equivalent to the sides of a ladder. A purine (Adenine or Guanine) will form hydrogen bonding with complementary pyrimidine (Cytosine and Thymine) based on the electronegative O, N interaction with the electropositive H. So, that's why Guanine and Cytosine make up a nitrogenous base-pair because their available hydrogen bond donors and hydrogen bond acceptors pair with each . Purines, from which adenine is derived, are found in plants and animals. FREE SOLUTION: Q22P A typical bacterial DNA has a molar mass of 410. Adenine always pairs with thymine, and cytosine always pairs with guanine. Thymine (DNA) and Uracil (RNA) are functionally similar, therefore they are also structurally similar. Since mRNA is single-stranded, there is usually no pairing in this molecule. HIGHLIGHTS. In the skeletal formula, most hydrogens are not shown and carbons are depicted as bends and ends in the lines. d) DNA synthesis On the other hand, guanine forms a pair with cytosine in both RNA and DNA. One molecule of DNA can contain hundreds even millions of nucleotides. For example, if we have the sequence 5'-ATCTC-3' on one chain, the opposite chain must have the complementary sequence 3'-TACAC-5\. The phosphate group and sugar are the same in every nucleotide, but there are four different nitrogenous bases: guanine, adenine, thymine and cytosine. Chemical structure.
