After hedgehog protein splits , the two fragments have different biochemical properties and are found in different areas of the developing fruit fly One fragment may direct the development of cells more distant from the site of its production , while another gives cues to cells near the area where it was produced . The protein seems to act like a stage director giving cues to performers in a play . These are the charges which providers are assessing to pay for the expansion of ` universal service ' in the form of the ` schools and libraries ' program . First , as I have stated previously , the size and scope of the current schools and libraries program is in excess of what was envisioned by Congress , and thus beyond the Commission 's authority to establish . However , it is also true that the retirement of the Boomers comes as no surprise to anyone . This starts the message to the brain about the new position . The Commission stated its understanding that Congress ' request concerning revision of the administrative structure was sparked in part by a recent letter from the General Accounting Office ( GAO ) which concluded that the Commission lacked authority to direct the National Exchange Carrier Association ( NECA ) , as a condition of its appointment as temporary universal service administrator , to create separate entities for the purposes of administering support for schools and libraries and rural health care providers .
