Hypersensitive site

In genetics a hypersensitive site is a short region of chromatin and is detected by its super sensitivity to cleavage by DNase I and other various nucleases (DNase II and micrococcal nucleases). In a hypersensitive site, the nucleosomal structure is less compacted, increasing the availability of the DNA to binding by proteins, such as transcription factors and DNase I. These sites account for many inherited tendencies.
