"Mendel described the way units of inheritance (which he called "genes") become associated and arranged in pairs on what are called "chromosomes". He emphasized the rules of assort- ment by which pairs of genes un- ravel. Gell Machinery "Scientists today are not as concerned with these aspects of cell machinery as they are with simpler kinds of chromosomes. In bacteria, we can think of the chromosomes as simple molecules; in man, the arrangements are too complex, and it is more accurate to consider the chromosomes as molecular a g g r e g a t e s," Prof. Hotchkiss explained. He added that when the link- ages between genes break down, this process occurs in regular fashion according to recognizable natural laws.

Sep- arate DNA molecules behave in- dependently of each other, he added. Cell Nucleus DNA bacterium resides in the nucleus of .the single cell that constitutes the organism. The structure of this complex material has been greatly publicized in re- cent years, so that now many lay- men as well as scientists are cog- nizant of its makeup, Prof. Hotch- kiss commented. He des ribed the DNA molecule as two chains of sugar phos- phates, forming a double spiral about each other and loosely con- nected by the bases adenine, guanine, thymine and cytosine. Prof. Hotchkiss explained DNA's role as a carrier of genetic "in- formation" in terms of an analo- gy between DNA and students. In one form of information trans-I fer, the necessary chemicals are passed from one bacterium to an- other in a highly organized fash- ion. Future Information "Future information is passed over later, but the first set of hereditary information may be neglected, much as a student might forget earlier chapters of a text after taking the mid-term examination," he noted. "Modemn laboratory techniques can transfer DNA from a cell that is resistant to a given drug to one that is not. This 'robbing of Peter to pay Paul' will transfer the characteristic immunity to the second cell. In so doing, the re- searcher can hypothesize the ways in which such transforma- tions might come about in na- ture," Prof. Hotchkiss said. Although the' resistance (or lack of it) that a bacterium shows toward a certain chemical is an important trait to the geneticist, he is also interested in the bac- terium's ability to cause fermen- tation on particular sugars and not others, the antigens that a bacterium might form and the response of bacteria to certain nu- trients. Prof. Hotchkiss also noted that by heating DNA to special tem- peratures between set extremes, one can destroy- the activity of certain gene-like molecules and yet keep others fully active. 1 ROARING TWENTIES HOMECOMING-Reviewing the schedule of events for the "weekend of weekends" on campus, these stu- dents are contemplating what sort of entertainment, excitement and just plain fun they will seek for Homecoming. The theme this year is the "Roaring Twenties" bringing back memories and events of the Universities first homecoming 40 years ago. Homecoming Recreates Roaringtwenties Era * (Continued from Page 1) He further pointed out that what he considers to be an ap- parent duplication is an expensive one. "If it is estimated that it costs the typical candidate about $20 to take the achievement tests, and if there were about 300,000 of them in 1962-63 (probably a con- servative ,estimate), then the total cost of $6 million becomes a figure of some consequence." After submission of the report, and his statistics on the validity of the exams, Prof. Fricke received word from the CEEB: They refus- ed to scrap the achievement tests, or set up a neutral board bf test-' ing experts to examine them - ,a compromise suggestion in the re- port. However, CEEB Executive Vice- President Richard Pearson will be in Ann Arbor late this month and has asked to meet with Prof. Fricke to discuss possible improve- ments in the test. Times Review Fred Hechinger, education edi- tor of The New York Times, re- viewed the Fricke report, and warned in his column last Sunday: "Whatever the outcome, it is im- portant that existing tests; be, ap- praised critically and open-mind- edly." "The time to do this is now- before the great new tide of appli- cants. A year from now adds to college admission pressures." Inherent Fault Prof. Fricke wrote in his report to the CEEB that an important reason why the achievement tests cannot be "improved" is that they inherently ,"tend to measure very 'few dimensions of consequence in college success." s "Non-academic elements" cru- cial to academic achievement in college are not measured by the achievement tests, but are scien- tifically measured by his own OIAS exam, Prof. Fricke claimed. The exam has been taken by entering freshmen in all schools of the University since 1957. Pop- ularly known as the "raw carrots" test, it measures several qualities in a student: 1) academic motiva- tion, 2) creative potential, 3) so- cial acceptability, and 4) degree of interest in the fields of busi- ness, biological and physical sci- ences, social sciences and human- ities. Defines Achiever Further, the exam measures a general quality possessed by "the achiever personality," a score which correlates highly with first- year grade point averages of Uni- versity students. In his report to the CEEB, Prof. Fricke wrote, "Many colleges in re- cent years have been receiving many more applications for admis- sion from "ability-qualified' stu- dents than they can admit. "Accordingly thenadmissions of- ficers ... have almost from neces- sity made discriminations based on procedures and data having lit- tle or at least unknown validity. Personality assessment is being carried out.! The tools and thedata may not be good--but they are used." Differentiation Prof. Fricke explained that his test was constructed on the basis of a series of experiments which separated those answers given by students with high grade point averages, and which given by less- er achievers. Among the data derived from University students by Fricke's test is evidence that those scoring high increativity, but average or low in academic motivation, tend to get lower grade point averages than those with average scores in both creativity 'and academic motiva- tion. :Y r Y 'r 1 (Continued from Page 1) Losh of the astronomy depart- ment.

' J s . a Two University professors and a Harvard University economist discussed the future .of the na- tion's economy before the 11th annual Conference on the Eco- nompic Outlook held yesterday. Prof. Harvey E. Brazer of the economics dept. told the confer- ence that as long as Congressional attention focuses strongly on a balanced national budget, the out- look for rational fiscal policy for the nation remains dim. Congressmen must understand that "a balanced administrative Econonists Predict Future For U.S. fiscalProgram "S COME ONE, COME ALL EVIL GOOD UNION JOCKS DAILY GUYS TO THE FOURTH BI ER ANNUAL BOWL Ron 'Fearless' Wilton Ray 'The Rams Rusnak Bob 'Porky' McKenzie MICHIGAN DAILY LIBELS vs. MICHIGAN UNION UN DESI RABLES TODAY a fn fl ii II I ~i II the inter-arts magazine NOW CONSIDERING FOR PUBLICATION IN THE DECEMBER ISSUE: ART - - it I MI it I it , I 'j { i i I Another speaker, Prof. Eva L. Mueller of the Survey Research Center, claimed that stimulation in the form of atax cut Orin- creased investment activity will be needed in 1964 to keep the econ- omy rising. She predicted a slowly rising level of consumer spending in the first half of 1964. "The moderately optimistic state of consumer confidence, therising rate of personal incomes and the currently rising marriage rate all point in that direction," Prof. Mueller said. GNP Rise A third speaker, 'Prof. John Lintner of Harvard University, predicted that the Gross National Product will pass the $600 billion mark and move into the $605-608 billion range in the first half of 1964. He claimed that the economy would make this record whether or not the administration's bill for tax reduction is passed. He added that if the tax cut is permanently sidetracked the an- nual total for GNP for 1964 will be at about the $605-608 billion level, industrial production and corporate profits would be lower and unemployment rates would be higher. Tax Cuts Prof. Lintner predicted that if the present proposed tax reduc- tions are passed by March and retroactive to Jan. 1, then the economy will expand vigorously throughout the year. If the tax bill is further delayed, he continued, but still passed in the second quarter and effective July 1, unemployment would de- crease and a small increase in corporate profits and capital spending within the year would Gerry 'Good Heart' Storch budget has no particular value in the. context of the operation of the economy as a whole," he asserted. Deficit Concerz The current Congressional con- cern on the size of the budget deficit, Prof. Brazer continued, makes it difficult to achieve a fiscal policy to meet the needs of an economy that has failed for six years to gain anything ap- proaching full employment. Prof. Brazer, recently returned from serving two years as Deputy assistant Secretary of the Treas- ury, told the conference that the administration, in asking for'. a tax reduction, has promised "the most. prudent possible policy of expenditures." The price, in terms of curtail- ing expanditures must be paid before delivery of tax reduction, Prof. Brazed said. "But included in th eprice may have to be desirable expansion of federal programs. The possibility that fiscal policy will, in the short run, be defla- tionary rather than expansionary must also be considered." Stimulus Needed m m y f .. I
