What is Gene Editing?
Gene editing is the modification of DNA. The traditional method consists of using restriction enzymes to cut a specific sequence. This method is a precise way to add or remove DNA in an organism. However, scientists are starting to turn to a more efficient method using CRISPR. CRISPR lets scientists pinpoint the exact location for cutting instead of depending on the less accurate restriction enzymes alone. Gene editing has the power to save and enhance lives, changing biology for the better.
How Does it Work?
In gene editing, a donor's DNA is required to modify a host’s DNA. Scientists cut out malfunctioning pieces of the host's DNA that are causing mutations. Then, the donor's DNA is inserted to replace that specific sequence. This is considered to be a permanent change to the host's genetic information.
There are many different methods that allow this process to occur.
