Genome editing technology
deals with engineered nucleases and it is the emerging type of genetic engineering. it is the technology in which the DNA is inserted, deleted or replaced in the genome. The emergence of highly versatile genome-editing technologies
has provided investigators with the ability to rapidly and economically introduce sequence-specific modifications into the genomes of a broad spectrum of cell types and organisms. It also promotes various changes in sub cellular level.genome editing itself also holds tremendous potential for treating the underlying various idiopathic genetic causes of certain diseases. The core technologies now most commonly used techniques to facilitate genome editing are clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9), transcription activator-like effector nucleases (TALENs), zinc-finger nucleases (ZFNs), and homing endonucleases or meganucleases.
