Polymerase chain reaction (PCR) is advance technique in recombinant DNA research with impact on molecular cloning and genetics. By PCR a target sequence of DNA can be amplified a billion fold in several hours. The different steps of PCR are Denaturation, Annealing and Primer extension.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
