Method of inhibiting expression of target mrna using sirna consisting of nucleotide sequence complementary to said target mrna

A inhibition method of target mRNA expression includes: (a) obtaining binding energy of a double combination section on a dsRNA sequence of all combination comprising complementary nucleotides to a random target mRNA; (b) dividing the binding energy into four sections on the dsRNA sequence of each combination to obtain a difference of the mean binding energy between each section and convert into a score of a relative combination energy pattern; (c) selecting siRNA whose inhibition efficiency to target mRNA is expected to be high by applying the converted score to the dsRNA sequence with other factors that affect the efficiency of siRNA; and (d) inhibiting target mRNA expression using the selected siRNA. As a result, a researcher or an experimenter can analyze patterns of a relative binding energy on base sequences of unknown siRNA without actual experiments to determine whether the siRNA is effective or ineffective rapidly, thereby design and production efficiency of siRNA can be maximized and target mRNA can
