You have designed a strain of transgenic mice using a viral promoter and a cdna coding for a human protein called p22. in most of the transgenic mice, you observe position-dependent expression of the human gene. suggest regulatory regions that you could link to the promoter- p22 dna construct that might confer position-independent expression. why would you choose these regions?

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
