Nucleic acid sequence Nucleic acid sequence A nucleic acid sequence is a succession of letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs
Nitroacetic acid by thermal decarboxylation of a corresponding salt to at 80 °C. Nitroacetic acid Nitroacetic acid is the chemical compound with the formula (NO)CHCOH. This substituted carboxylic acid is used as a potential precursor to nitromethane, commonly used as a fuel in drag racing and as an organic reagent in chemical synthesis. Nitroacetic acid can be synthesized by adding cold chloroacetic acid into a cold, slightly alkaline aqueous solution, followed by mixing with aqueous sodium nitrite solution. It is important during this procedure not to make the solution too alkaline and to keep it cold to prevent the formation of sodium
