C-DNA

C-DNA also known as C form DNA. It is one of the many possible double helical structures of DNA. This form of DNA could be observed at a relatively low humidity with certain ions, like Li⁺ or Mg2⁺.

Recent research suggests that both C-DNA and B-DNA consist of two distinct nucleotide conformations, B-I and B-II. The ratio of B-II conformation in C-DNA is more than 40%. However, the ratio of B-II conformation in B-DNA is only about 10%.
