user: Question: How many base pairs are there if the molecular weight is 102?
Columns: ['RNA Segment (Gene)', 'Size ( s base pair )', 'Protein', 'Molecular weight kDa', 'Location', 'Copies per particle', 'Function']
Types: ['real', 'real', 'text', 'text', 'text', 'text', 'text']
Sample row: [1.0, 3302.0, 'VP1', '125', 'At the vertices of the core', '<25', 'RNA-dependent RNA polymerase']
SQL:

assistant: SELECT SUM("Size ( s base pair )") FROM "Table" WHERE "Molecular weight kDa" = '102';
