Give two examples of how eukaryotic organisms derive benefits from regulating gene expression - 1) Rabbits change from brown to white due to a response to environmental changes 2) larval to adult is totally different b/c of different proteins during life changes gene expression control is used in multicellular organisms to. . . - define tissues and cells w/ specific functions w/in organism What is the order of regulation of gene expression - transcription, RNA processing, translation, post...

Replication correct answers DNA must be retained intact, yet copied to make new cells Transcription correct answers DNA must be turned into multiple "working copies" to provide instructions for enzymes/structural proteins production Translation correct answers RNA must be read and decoded to form the enzymes/structural proteins of the cell DNA repair correct answers systems must have the ability to deal with damage Transcription in Bacteria correct answers - involves RNA polyme...
