What are the methods used in step 1 (to isolate the Psy and Crt1 genes), step 2 (to amplification the Psy and Crt1 genes), step 3 (to transfer the Psy and Crt1 genes into the Ti plasmid), and step 4 (processes used to insert the plasmid back into a bacteria)?

the answer is golgi apparatus

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
