binnnt DXA will improve the understanding of funda- 
mental biological processes; 
(2) the knowledge gained from such research and 
other activities may he Qf great benefit to medicine and 
agriculture and may provide many other benefits to 
society; 
(3) there exist, however, uncertainties regarding 
the extent to which recombinant DXA or organisms or 
viruses containing recombinant DXA and activities in- 
volving recombinant DXA may present a ri>k of injur}' 
to health or the environment, and there is a risk that 
such organisms and viruses may spread quickly and 
without warning to persons, agricultural plants and prod- 
ucts, and other items in or affecting commerce; 
(4) the public interest require? that the health and 
welfare of the population of the United States be pro- 
tected from such risk, and commerce n the United States 
is dependent upon such protection being provided; and 
(5) to effectively accomplish such protection and 
consequently to effectively regulate commerce requires 
that the possession of recombinant DXA and any activity 
engaged in for its production (whether a research or 
commercial activity) be subject to control.
