Genome editing, or genome editing with engineered nucleases (GEEN) is a type of genetic engineering in which DNA is inserted, replaced, or removed from a genome using artificially engineered nucleases, or molecular scissors..enome editing with engineered nucleases will likely contribute to many fields of life sciences from studying gene functions in plants and animals to gene therapy in humans.
The polymerase chain reaction (PCR) is a powerful core molecular biology technique. It is an efficient and rapid in vitro method for enzymatic amplification of specific DNA or RNA sequences from nucleic acids of various sources.A simple PCR reaction consists of a set of synthetic oligonucleotide primers that flank the target DNA sequence, target DNA, a thermostable DNA polymerase and dNTPs.he polymerase chain reaction (PCR) is a powerful core molecular biology technique.
