23andMe is the first and only genetic service available directly to you that includes reports guide your life style. If you don't like your genes, you can change. No doubt, CRISPR/Cas8 system will help lead to the old Chinese way to change human fate, but for better or worse - only God knows. Heckuva unknown to me: Human acts as force of natural selection - fear nature or not fear nature? Your choice!
Clustered regularly interspaced short palindromic repeats (CRISPR, pronounced crisper[2]) are segments of prokaryoticDNA containing short repetitions of base sequences. Each repetition is followed by short segments of "spacer DNA" from previous exposures to a bacteriophage virus or plasmid.[3]
The CRISPR/Cas system is a prokaryotic immune system that confers resistance to foreign genetic elements such as those present within plasmids and phages,[4][5][6] and provides a form of acquired immunity. CRISPR spacers recognize and cut these exogenous genetic elements in a manner analogous to RNA interference in eukaryotic organisms.[3] CRISPRs are found in approximately 40% of sequenced bacterial genomes and 90% of sequenced archaea.[7][note 1]
The use of CRISPR for editing genes[8][9] was the AAAS's choice for breakthrough of the year in 2015.[10]
The CRISPR interference technique has enormous potential application, including altering the germline of humans, animals, and other organisms and modifying the genes of food crops. By delivering the Cas9 protein and appropriate guide RNAs into a cell, the organism's genome can be cut at any desired location.[11][12][13] CRISPRs have been used in concert with specific endonucleaseenzymes for genome editing and gene regulation in species throughout the tree of life.[14] Ethical concerns have been expressed about the prospect of using this nascent biotechnology for editing the human germline
