August 2017
In the largest attempt at altering embryos, American researchers successfully correct a hereditary heart condition using CRISPR.
2019
Scientists discover a new way to track accidental gene edits, or off-target mutations.
2016
Mushrooms are modified to reduce browning.

History of Gene editing
2012
Epigenetic editing is discovered. Epigenetics are based on the change of traits by gene expression.
2015
Pigs are genetically altered to develop human organs. There is hope of using them for organ transplants to save lives.
July 2014
An inducible lentiviral system is developed to deliver platform cells. This ensures a more efficient way of gene editing.
April 2014
Human-related genes in mice are cured by using CRISPR/Cas9 to correct a mutation.
February 2014
Chinese scientists test CRISPR/Cas9 on live monkeys.
2013
The CRISPR/Cas9 system is tested on zebrafish.
1953
Francis Crick and James Watson discover that DNA is a double-helix structure.
1970s
Frederick Sanger and a group of researchers invent a way to read DNA. It is called genome sequencing.
1990-2003
The Human Genome Project, the concept of mapping the human genome, is complete.
