【多选题】Which of the following statements about "IASB: Technical Solutions for Biosecurity in Synthetic Biology (2008)" are correct?
A.
The assembly of artificial DNA into functional genes and the production of proteins from such genes is available as a highly standardized commercial service. This international industry currently fills thousands of orders for whole genes and millions of orders for short oligonucleotides each day.
B.
In some instances, these orders comprise DNA sequences derived from pathogenic organisms, and in rare cases from pathogens with an extremely high mortality rate, such as the Ebola virus.
C.
The most frequently cited lists of biological agents with potential to pose a severe threat to public health and safety are published by the US Federal Register, FDA, NIAID, CDC, by the American and European Societies for Microbiology and by the WHO.
D.
There exist of course a number of national regulations that deal with biosecurity. Most countries, including the USA and EU members, have legislation in place for the limitation of the export of dual use goods. This includes synthetic DN
