Comparative molecular genetics technology

Change affects not only methodological aspects of laboratory work but equipment requirements as well. For example, thermal cyclers are a necessity in molecular laboratories today but were unheard of before the advent of PCR. PCR technology has also made it possible to do a good deal of comparative molecular work without the aid of ultracentrifuges or steam sterilizers, items that are expensive but irreplaceable components of a standard molecular genetics laboratory. Clearly, it behooves die researcher...
