How Gene editing CRISPR Cas9 work


CRISPR is a technology for changing the
sequence of DNA in cells in a precise fashion to correct mutations that might
otherwise cause disease. It’s going to enable a lot of science to be done that
was impossible to do in the past. So the way the CRISPR technology works is by the
action of a protein called cas 9 that functions like a molecular scale for DNA. The CRISPR cas 9 system has an amazing ability to recognize a particular DNA
sequence in the cell but maybe not functioning and then disable it by
cutting the DNA we call this gene editing and we can use it to disable or
repair a mutated part of the gene which may be causing disease. For cas 9 to
find a malfunctioning DNA attach it to an RNA sequences that matches the DNA
sequence we want to edit, then we put this RNA cas 9 combination into the
cell that finds the new DNA and use the chemical reaction to cut the DNA strand right of
the spot where it’s malfunctioning, after that we can sometimes insert the correct
version of the gene for the cell to work properly again
