WebMay 16, 2016 · The DNA in our cells twists like a right-handed screw (pictured, bottom); a mirror-image polymerase enzyme is needed to copy left-handed DNA (pictured, top). Credit: Zixuan Li, Xin Tao, Ting F. Zhu. WebThe most common form of DNA which has right handed helix and proposed by Watson and Crick is called B-form of DNA or B-DNA. In addition, the DNA may be able to exist in other forms of double helical structure. These are A and C forms of double helix which vary from B- form in spacing between nucleotides and number of nucleotides per turn ...
