Thus, to make nucleic acids for cell proliferation purposes, cells have to upregulate both energy metabolism and the nucleotide biosynthetic pathways. Nucleic acid metabolism is the process by which nucleic acids are synthesized and degraded. A nucleic acid in aqueous solution is in equilibrium between the native conformation and its uncoiled conformation. Nucleotides and Nucleic Acids Chapter 8 Lehninger 5th ed.

ADVERTISEMENTS: The following points highlight the six major diseases caused due to errors in nucleic acid metabolism. who discovered nucleic acids in 1871. Disorders of nucleic acid metabolism- hyperuricemia,hypouricemia,gout NUCLEIC ACIDS AND THEIR. 1. See our User Agreement and Privacy Policy. The nucleus contains the cell’s DNA, which makes up the genome. Nucleotide synthesis is ananabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base. Friedrich Miescher Introduction to Nucleic Acids. The metabolic requirements for the nucleotides and their cognate bases can be met by both dietary intake or synthesis de novo from low molecular weight precursors.Indeed, the ability to salvage nucleotides from sources within the body alleviates any significant nutritional requirement for nucleotides, thus the purine and pyrimidine bases are not required in the diet.

Objectives By the end of lecture the student should: Define nucleic acids. RNA not only stored and propagated genetic information, a role that is almost universally filled by DNA in current life forms, but it also realized and expressed this information, which in current life forms is mostly accomplished by proteins. METABOLISM Naresh panigrahi Gitam university Nucleic Acid. Lesch-Nyhan Syndrome: a. In addition to these direct effects, alterations in the metabolism of proteins or nucleic acids may be consequent to the effect of the drug on other metabolic processes such as transport or energy supply. For example, they are: • Substrates (building blocks) for nucleic acid biosynthesis and repair, • The main storage form of “high energy phosphate”, • Components of many “so-called” co-enzymes (NAD, NADP, FAD, CoA), • Components of many activated metabolic intermediates (such as UDPG, SAM), 8. 3.
