DNA which is structurally similar to B- and Z-DNA, has a right-handed helical structure, but is shorter, more compact and occurs only in dehydated DNA samples. It is one of several double-helical forms of DNA, which can also be assumed by DNA-RNA hybrid helices and by regions of double-stranded RNA.
One of the three forms of DNA. This form is found in DNA gels with relatively little water. It is a right-hand helix with about 11 bases per turn.
