Most of the nucleotide is present as the triphosphate and the ATP/ADP ratio ranges from 10 to 20. Relatively small amounts of the monophosphates are present. Guanine nucleotides make up a fairly large proportion of the nucleotide pool of the brain, more so than in other tissues of the ...
Molecular studies indicate that bacterial and animaladenine phosphoribosyltransferase(APT) and hypoxanthine/guanine phosphoribosyltransferase (HGPT) proteins belong to the phosphoribosyltransferase (PRT) family (Craig and Eakin, 2000; Liu et al., 2007; Sinha and Smith, 2001). Structurally, the PRT prot...

the adenine–thymine base pair and three hydrogen bonds between the guanine–cytosine base pair. Thus, GC base pairs are stuck together a little stronger than AT base pairs. The two DNA strands form a twisted ladder shape or double helix due to this ‘base-pairing’ phenomenon (Figure 2.2)...
