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