Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: 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?

### Accurate SQL ###

SELECT copies_per_particle FROM table_name_88 WHERE location = "nonstructural" AND rna_segment__gene_ > 5 AND size___s_base_pair__ < 751
