Plant Immunity, Nonhost resistance during plant-pathogen interaction and mechanism of PCD
Thermocyclers, or thermal cyclers, are instruments used to amplify DNA and RNA samples by the polymerase chain reaction. The thermocycler raises and lowers the temperature of the samples in a holding block in discrete, pre-programmed steps, allowing for denaturation and reannealing of samples with various reagents.
In molecular biology they are used for DNA sequencing, cloning, generation of probes, quantification of DNA and RNA, studying patterns of gene expression, detection of sequence-tagged sites, and many more techniques.
