CREATE TABLE table_name_88 (copies_per_particle VARCHAR(255), size___s_base_pair__ VARCHAR(255), location VARCHAR(255), rna_segment__gene_ VARCHAR(255))
What is the number of copies per particle having a nonstructural location, an RNA segment over 5 and a base pair size under 751?
    
SQL: SELECT copies_per_particle FROM table_name_88 WHERE location = "nonstructural" AND rna_segment__gene_ > 5 AND size___s_base_pair__ < 751
