Hachimoji DNA

Hachimoji DNA is a type of DNA that consists of eight different letters, instead of the usual four letters. These eight letters are four regular DNA letters (A, C, T and G) and four extra letters (B, D, H and V). This type of DNA is sometimes found in creatures that have adapted to live in extreme environments, like deep-sea vents or hot springs. Hachimoji DNA can help scientists understand how these creatures were able to survive in such harsh conditions.
