Help Wanted
Positions Available in the genetics industry. Hundreds of entry-level openings
for tireless workers. No previous experience necessary. Must be able to transcribe
code in a nuclear environment.
Accuracy and Speed vital for this job in the field of translation. Applicants
must demonstrate skills in transporting and positioning amino acids. Salary
commensurate with experience.
Executive Position available. Must be able to maintain genetic continuity
through replication and control cellular activity by regulation of enzyme
production. Limited number of openings. All benefits.
I
Secretary of production of proteins-all
shifts. Must be able to transcribe exact
directions from double-stranded template. Travel from nucleus to the ribosome is
additional job benefit.
