Shaped charge jet formation
WebbHigh content of positively charged amino acids allow them to closely associate with negatively charged DNA. Heterodimers, or histone-only intermediates are formed from histone-fold domains. The formation of histone only-intermediates proceeds when core histones are paired into the interlocked crescent shape quasi-symmetric heterodimer. WebbIn order to enhance the penetration capability of the shaped charge jet, different liner forms are used. These modifications help to increase the jet tip velocity, as well as to improve …
