You mean the reflex action?
When the receptors detect stimuli, the electrical impulse passes along the sensory neuron across a synapse in the CNS, whit is transmitted across the synapse by chemicals, it passes onto the delay neuron and then across another synapse, before passing to the motor neuron where the effector will receive it and create a response!

Synapse is the distance between two neurones

Reflex:

Receptors in the skin detect the stimulus and send an electrical impulse along the sensory neurone. Chemicals are released and are diffused across the gap (synapse) and attach onto the next neurone. The impulse is sent along the motor neurone via synapse till it reaches the muscle and it contracts (response)

genetic engeneering cut desirable gene and cut plasmid using restriction enzyme. The cut plasmid is now a vector. Stitch desirable gene into vector using ligase. Now you need to multiply the genetically engeneered thing do this by putting it into something such as a bioreactor/fermenter

Hope that helps for genetic engeneering
