Plasticity of Secondary and Tertiary DNA Structure

Description
Z-DNA is a left-handed helix with alternate
purine/pyrimidine bases in alternate syn/anti conformation.

Purines are syn.

Pyrimidines are anti.

There is now abundant evidence that Z-DNA exists in living cells.

The exact role played by Z-DNA in vivo is still an open question.
