Few, if any, of the enzymes that are designed to function with DNA are structured to work on left-handed DNA. I am not a biologist, so I don't know which enzymes can function with left-handed DNA, sorry! What I *do* know is that the enzymes are basically tiny molecular machines.

The Short Answer

Few, if any, of the enzymes that are designed to function with DNA are structured to work on left-handed DNA. I am not a biologist, so I don't know which enzymes can function with left-handed DNA, sorry! What I *do* know is that the enzymes are basically tiny molecular machines. Like real, full-scale machines, they aren't "smart", they can't think about what they're working on. They can only fit around the molecules that they are constructed to fit around. [They're actually really incredible machines!](_URL_0_) Left-handed DNA doesn't change the order of the nucleotide instructions that code for those enzymes. The instructions don't change, so the enzymes that are made with it are the same right-handed enzymes. It's a bit like trying to use a flat-head screwdriver on phillips-head screws, and the screws are on a machine that makes flat-head screwdrivers.
