Apparatus and method for automatically developing, maintaining and repetitively duplicating a selectable predetermined temperature profile for replicating and amplifying a sequence of a stretch of DNA or RNA through use of a polymerase. An array of sample-containing vessels is supported in a reaction chamber through which a heat transfer medium in heat-exchange relationship with the vessels. The temperature of the air is controlled as a function of time to provide a preselectable sequence defining a temperature profile. The profile is cyclically repetitively reproduced to effect amplification of the desired sequence of DNA or RNA.
