defined the relative contents of particular length variants in the thousand gemmules of the specimen V2 as an example. The amplicon. The part of the sequence that was used for comparison relative amounts of the ITS1 sequence variants of different length comprised of at least 200 nt following an indel position. and variants containing the substitution in Position 169, found in Since we found different annotations in NCBI GenBank for the these different PCR experiments are presented in Table 1. The borders of E. fluviatilis ITS sequences, we aimed to avoid further results from the substitution analysis are rounded to integer confusion about the lengths of ITS sequences described and percentage values, because when analysing a substitution, infor-

Prokarüootsete organismide, eriti bakterite puhul võib DNA vabastamiseks bakterirakku kuumutada üle 90°°C. PRAIMERI SEOSTUMINE (ANNEALING). Praimer on lühike nukleiinhappe lõik (oligonukleotiid pikkusega 20-30 nukleotiidi), mis vastavalt komplementaarsusele seostub (annealing) teatud kindla nukleiinhappe järjestusega. Igal mikroorganismi liigil, geenil, operonil on mingi unikaalne järjestus, mida on võimalik määrata sekveneerimisel, leida need andmed andmebaasidest (GENBANK jne.). Praimerid valitakse ja disainitakse nii, et nad asetseksid huvipakkuvast geenist või nukleotiidide järjestusest „väljaspool“ ja nende vahele jääks 50 kuni 1000 nukleotiidipaari. Kui praimerid panna koos denatureerunud sihtmärk-DNA-ga lahusesse, seostub üks praimer ahela ühele spetsiifilisele kohale (sait S1), samas kui teine ahela teisele kohale (sait S2). Praimerite seostumise protsess toimub temperatuuril ≥50º-58ºC. KOMPLEMENTAARSE AHELA SÜNTEES
