B-Form and Z-Form DNA

Caption

The normal (B-form) DNA will switch to left-handed (Z-form) DNA when it is physically twisted, or when a lot of salt is added to the solution. Researchers at the University of Luxembourg were able to accurately calculate for the first time the amount of salt which is required to do this. Z-DNA in the cell leads to loss of function and cancer.
