Genetic variability of three sympatric crucian carp ( Carassius carassius ) populations from NW Poland was studied within a research project aimed at assessing the utility of those populations for stocking in inland waters. DNA samples were collected from 65 individuals. Restriction analysis was performed using 4 enzymes (HaeIII, HinfI, FspBI, TasI) of known restriction sites. The restriction pro files obtained were classified as belonging to a single haplotype (H-1). Selected DNA products were sequenced; the subsequent comparison made it possible to detect the presence of substi- tutions in the genome fragment analysed.
W pracy przedstawiono przegląd metod analizy ekspresji genów z zastosowaniem technik: mikromacierzy DNA, seryjnej analizy ekspresji genów (SAGE), jak również odwrotnej transkrypcji – RT-PCR oraz qRT-PCR. Zaprezentowano możliwości wykorzystania poszczególnych technik wraz z przykładami ich praktycznego zastosowania w badaniach molekularnych rzepaku.
