Does Z-DNA Play a Regulatory Role? | Genetics

Get the answer of: Does Z-DNA Play a Regulatory Role? One of the more interesting discoveries of the last decade was that segments of DNA that have sequences in which purines and pyrimidines alternate along each strand can form left-handed double helices. The Watson-Crick B-form of DNA is a right-handed double helix. The novel left-handed double-helical form of DNA has [...]
