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.
Polymerase chain reaction (PCR) is a method that allows exponential amplification of short DNA sequences. (usually 100 to 600 bases) within a longer double stranded DNA molecule. PCR entails the use of a pair of. primers, each about 20 nucleotides in length, that are complementary to a defined sequence on each of the. two strands of the DNA. These primers are extended by a DNA polymerase so that a copy is made of the.
