★ 08/17/09 to 08/21/09 ---parts construction

[counter group】

Cut plasmids by restriction enzymes and pick up RBS and taRNA-Term. Ligate these parts and DH5a

was transformed with sample. Do same things with following parts.

This chart suggests that we pick up part 1 and part 2 materials, ligate them, transform DH5a with them,

inoculate that cell and do miniprep after cultivation.
