Superhelix

Superhelix refers to structures that are highly twisted forms of a double helix, often found in molecular biology and biochemistry. Specifically, in the context of DNA, a superhelix is a form of DNA that is further twisted beyond the normal helical structure, resulting in supercoiling. This supercoiling is an important aspect of DNA structure that plays a critical role in processes such as DNA replication, transcription, and packaging within the cell nucleus.
