Whereas gene editing involves changing the actual DNA sequence itself, epigenetic editing involves modifying and presenting DNA sequences to proteins and other DNA binding factors that influence DNA function. By "editing” epigenomic features in this manner, researchers can determine the exact biological role of an epigenetic modification at ...
Genome editing, or genome engineering, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism. Unlike early genetic engineering techniques that randomly inserts genetic material into a host genome, genome editing targets the insertions to site-specific locations.
These tools use different mechanisms to bind a predetermined sequence of DNA (“target”), which they cleave (or "cut"), creating a double-stranded chromosomal break (DSB) that summons the cell's DNA repair mechanisms (non-homologous end joining and homologous recombination ) and leads to site-specific modifications.

It has since been adopted for use as a tool in the genetic engineering of higher organisms. Designing an appropriate gRNA is an important element of genome editing with the CRISPR/Cas system. A gRNA can and at times does have unintended interactions ("off-targets") with other locations of the genome of interest.
After discovering the existence and properties of DNA, tools had to be developed that allowed it to be manipulated. In 1970 Hamilton Smiths lab discovered restriction enzymes, enabling scientists to isolate genes from an organism's genome. [4] DNA ligases, which join broken DNA together, were discovered earlier in 1967. [5]
