New report - frequently asked questions about CRISPR & Co
22 October 2020 / Testbiotech is publishing a new report today on New Genetic Engineering (New GE) that shows why these techniques need to be strictly regulated. New GE - or ‘genome editing’ - opens up new possibilities which go way beyond conventional breeding and previous methods of genetic engineering. One of the most important tools in this scenario are CRISPR/Cas gene scissors (nuclease). In contrast to chemical or physical mutagens used in conventional breeding, tools such as CRISPR/Cas can directly interact with biological mechanisms in the cells.
Recent research clearly shows that there are major differences in New GE compared to conventional breeding: over the course of evolution, mechanisms have emerged which can protect specific genomic regions against too frequent mutations. These mechanisms can be described as the ‘flexible safety barriers’ of evolution, and are also effective in conventional breeding. They appear to be relevant to regions in the genome that are of some importance to the survival of a species. New GE is designed to circumvent these mechanisms.
