MSH: In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.,CSP: method for reproducing specific DNA sequences based on elongation of complementary primers by DNA polymerase; primarily used to increase quantities for analytical detection of, e.g., virus genome.,NCI: A laboratory method used to make many copies of a specific DNA sequence.,CHV: laboratory procedure for producing large amounts of specific DNA or RNA
