Understanding selectivity in the CRISPR CAS9 system

In this system, off-target binding must be reduced to a minimum because its occurrence can lead to modifications of genes rather than the ...

DNA unit Summary
... DNA, there are four possible nitrogen bases – adenine (A), guanine (G), cytosine (C), and thymine (T). In DNA, nucleotides combine to form two long chains that intertwine with each other, like a ladder that has twisted into a spiral. Another name for this spiral is the double helix (double because t ...
