First genetically modified humans could exist by 2017
Developing the new CRISPR genetic therapy technology is taking us steps closer to being able to fully edit our own genes. CRISPR stands for Clustered, Regularly Interspaced, Short Palindromic Repeat and is a naturally-occurring defense mechanism used by bacteria. Like a pair of “molecular scissors,” bacteria carries the DNA of certain viruses so it can recognize them when they appear. When they see them, the bacteria will hook up to the viral DNA and cut out the mutated piece of the strand. Scientists have figured out how to manipulate this process and use it, at will, on viruses and...
