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_926 ( "RNA Segment (Gene)" real, "Size ( s base pair )" real, "Protein" text, "Molecular weight kDa" text, "Location" text, "Copies per particle" text, "Function" text )

### Question ###
How many base pairs are there if the molecular weight is 102?

### Accurate SQL ###

SELECT COUNT("Size ( s base pair )") FROM table_926 WHERE "Molecular weight kDa" = '102'
