Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
What is the number of copies per particle having a nonstructural location, an RNA segment over 5 and a base pair size under 751?

### Inputs:
table_name: table, columns: ['RNA Segment (Gene)', 'Size ( s base pair )', 'Protein', 'Molecular weight kDa', 'Location', 'Copies per particle']

### Response:
SELECT Copies per particle FROM table WHERE Location = nonstructural AND RNA Segment (Gene) > 5 AND Size ( s base pair ) < 751
