Sugar Transporter Protein

Caption

This image shows the production of a sugar transporter protein (yellow dots) in the bacterium E. coli in response to sugar in the environment. Grey dots are ribosomes. Pink circles represent messenger RNA. Green circles are repressor molecules that shut down transcription when they bind to the sugar transporter gene in the bacterial DNA (purple zone).
