The Michigan Daily Vol LXXXVII, No. 19-S Ann Arbor, Michigan-Saturday, May 28, 1977 Ten Cents Twelve Pages Researchers stud DNA mystery By SUE WARNER A year ago this month the Regents gave their approval for recombinant DNA research at the University. Since then, several University researchers have been performing recombinant DNA ex- periments in an attempt to answer some of the biologicalquestions which have continually baffled scientists. Basically, recombinant DNA research involves combining the genes of one or- ganism with those of another-to create a new life form which does not breed naturally. THE PURPOSE of this procedure is to isolate specific genes and transfer them into another organism in order to observe the particular gene's effect on the organism. Previously, it was impos- sible to study individual genes or even sets of genes because of the complex structure of the chromosomes.' Recently questions have been raised, over the safety of such research-whether scientists might produce a new organism that could prove harmful to the environ- ment. Dr.,Roy Schmickel, professor of pedia- trics and communicable diseases at the Univeristy's Medical School, said he feels there is little cause for concern about the possibility of some new, destructive life-form escaping from the lab. "Theo- retically, the potential is there to make new life, and that's what people are worrying about. But that kind of thing is not included in any research now." SCHMICKEL is currently involved in studying the organization of a single human gene, a project which was im- possible before the advent of recombi- nant DNA research. - "Humans have DNA for six million genes and it's hopeless to try to study one gene- in that complicated mix," he explained. "But, if you take the gene and put it in a simple environment such as a phage (form) which has only 30 genes, it's easy to study." Schmickel said he hopes his research will eventually help to at least reduce, the incidence of human genetic diseases. "My question is, why are chromosmal diseases in humans so common?" SCHMICKEL would like to discover why, for example, older women give birth to a higher percentage of children suf- fering from Down's syndrome (Mon- galism), a genetic disease causing re- tardation.- "It's not something that just happens randomly," Schmickel said, "the process can be slowed down or reversed. That's the rationale for doing the research." Two other researchers, Dr. Robert Helling, associate professor of biology, and assistant research scientist Margaret Lomax are using DNA technology to study the process of photosynthesis in plants. THE RESEARCHERS- are studying genes located in the chloroplasts of a green algae. First, they must isolate the chloroplast from the cell and then the DNA from the chloroplast. The DNA is then cut with an enzyme and the frag- ments are spliced into Ecoli, a form of bacteria often used in research. The bac- teria then begins to grow, allowing the chloroplast genes to be easily studied. Lomax explained her attitude towarc the research, "We look at it in terms o1 increasing our knowledge of a more complex cell. Also, we don't know a lot about the process of photosynthesis, and it's obviously an important process. Trap ping light and converting it to energy is essential to life on Earth." University researchers currently oper ate under guidelines suggested by the National Institute of Health. These guide lines specify the four levels of risk it recombinant DNA experimentation. THE P-S and P-2 levels are relatively safe. Experiments of this degree car proceed under normal laboratory condi tions without taking special precautions P-3 level research has been proposer and approved at the University, pending the renovation of two labs to meet highet See 'U', Page 5 Dutch police key on train ASSEN, The Netherlands I) - Heavily-armed Dutch troops and police turned their attention to South Moluccan extremists- holding 55 hostages on a sweltering train following the release of M ,5 105 children from a village schoolhouse earlier yesterday. Four* s ss other hostages, all teachers, remained captive in the school. Reporters heard what sounded like two rifle shots fired from Vt one direction of the train but there was no immediate explanation of what caused it. The reporters said they saw the terrorists shak s ing out blankets and throwing out garbage about the time the 9 sounds were heard. THE SOUTH Moluccans, -=ho want the Dutch government to press their demands f=r the independence of their Pacific island from Indonesia, have askced the release of 25 fellow extremists jailed for terrorist actisities and a jumbo jet to take them - and a group of hostages - to an undisclosed location. Dutch Prime Minister, Joop den Uyl told a news conference the situation at the train was "still very serious" despite the en- couraging release of the schoolchildren. Den Uyl reiterated the go-ernment is not negotiating with the extremists and will not agree to hostages being transported out of the country. POLICE and troops, back-d by machine gun-mounted armor- ed personnel carriers equipped .with infrared night sights, have encircled the commuter train in flat lush farmland 10 miles north of this town where seven South Moluccans hold 55 hostages. The inner security ringe is three quarters of a mile from the four car blue and yellow train. y Patrols, including sharpshooters, are stationed in woods on the outer ring. Among the hostages on the train are 20 women and 35 men, including at least seven teen aged students and a pregnant wo- man suffering from thyroid trouble. Officials say she is being provided with regular m]dication. v "IMAGINE yourself in a metal box, in the hot sun. The tem- perature must have risen to at least 30 degrees Centigrade (104 Fahrenheit). The windows are closed all day," said one railway official describing the situation inside the train. The terrorists on the train, one of them a woman, seem more edgy than those in the scho.l and on Wednesday and Thursday displayed some of their bound hostages, blindfolded and dressed in white - the Orient'i color of mourning. After refusing any supplies for over S hours, the group accepted hot meals, fruit yogurt and even clean underwear on Thursday. In the nearby villa,,e of Bovensmilde, where four teachers including two women - are still held, 76 of -the released children were reunited with their families. Twenty-six others remained in hospitals for examination after they developed stomach ailments Dily Photo by ALAN BILINSKY that led to their release.
