High energy proton is an important type of the space radiation. The paper investigates the radiation effect of high energy proton (27.9 MeV) on DNA aqueous solution in the field of the molecular mechanism. The following information about the microcosmic damage to the space structure of DNA was obtained: (i) breakage of a part of interbase hydrogen bonds which maintained double helical structure of DNA; (ii) damage on four bases, in which the damage on adenine ring was the most serious; (iii… CONTINUE READING
