Nucleic acids reactions

What is the difference between a living horse and a one which has just died They have the same amount of RNA, DNA, and all nucleic acid reactions are working for a while. Why is the dead horse dead ...

Because of the polyelectrolyte effect (Section 3.1), the rate of metal-polynucleotide reaction to form coordinative-covalent bonds will depend on the positive charge of the metal species accordingly, the rate can be increased significantly by introduction of additional positive charge to the reagent, for example, [(NH3)2PtCl(H20)]+— [(NH3)2Pt(H20)2] +. The rates of selected metal nucleic acid reactions are given in Table 2.

In this book, we concentrate largely on methods for the computer manipulation of small and medium-sized molecules, molecules of up to a few hundred or thousand atoms. We do this to develop an understanding of the methods available for the processing of information on chemical compounds and reactions. However, many of these methods can also be applied to macromolecules such as proteins and nucleic acids. 

Nucleic acid contents of SCP products, which range up to 16% in bacteria and 6—11% in yeasts, must be reduced by processing so that intakes are less than 2 g/d to prevent kidney stone formation or gout. Adverse skin and gastrointestinal reactions have also been encountered as a result of human consumption of some SCP products (87). 

Fohc acid is a precursor of several important enzyme cofactors required for the synthesis of nucleic acids (qv) and the metaboHsm of certain amino acids. Fohc acid deficiency results in an inabiUty to produce deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and certain proteins (qv). Megaloblastic anemia is a common symptom of folate deficiency owing to rapid red blood cell turnover and the high metaboHc requirement of hematopoietic tissue. One of the clinical signs of acute folate deficiency includes a red and painhil tongue. Vitamin B 2 folate share a common metaboHc pathway, the methionine synthase reaction. Therefore a differential diagnosis is required to measure foHc acid deficiency because both foHc acid and vitamin B 2 deficiency cause...

Results on DNA-based biosensors will be presented they have been used mainly for two kind of applications 1) for the determination of low-molecular weight compounds witlr affinity for nucleic acids and 2) for the detection of hybridization reaction. 

FIGURE 1.9 (a) Amino acids build proteins by connecting the n-carboxyl C atom of one amino acid to the n-amino N atom of the next amino acid in line, (b) Polysaccharides are built by combining the C-1 of one sugar to the C-4 O of the next sugar in the polymer, (c) Nucleic acids are polymers of nucleotides linked by bonds between the 3 -OH of the ribose ring of one nucleotide to the 5 -P04 of its neighboring nucleotide. All three of these polymerization processes involve bond formations accompanied by the elimination of water (dehydration synthesis reactions). 

Most reactions of nucleic acid hydrolysis break bonds in the polynucleotide backbone. Such reactions are important because they can be used to manipulate these polymeric molecules. For example, hydrolysis of polynucleotides generates smaller fragments whose nucleotide sequence can be more easily determined.
