    Notes: [Auszug] THE molecular cloning of genes and their transfer between different kinds of cells and organisms is now a standard analytical method, practised in almost every modern university biological department, and fill-ing more than half of the pages of the leading biological journals. Anxiety about its ...

    Notes: [Auszug] Sir John Ziman, reviewing Norman Levitt's book Prometheus Bedeviled (Nature 404, 811; 2000) calls reductionism a “busted flush”. But what is reductionism? Molecular biologists in particular tend to be accused of it, ...

    Notes: [Auszug] SUCCESSFUL plant breeding depends on a pool of genetic variation to which selection can be applied. But by producing highly productive varieties that take over large sectors of the market, its natural tendency is to drive much of that variation out of existence. At the same time, the reservoir of ...

    Notes: [Auszug] THE year 1944 saw the publication of a demonstration by Guido Pontecorvo and Alan Gemmell of segregation of genetic markers from heterokaryons in Penicil-lium notatum. They were greatly helped by two convenient features of the fungus - the asexually produced spores (con-idia) were uninucleate, and ...

    Notes: [Auszug] BARBARA McClintock has earned fame in three different ways. In the 1930s her brilliant and incisive cytogenetic studies were of great importance in the consolidation of the chromosome theory of heredity, and were recognized as such at the time. From the mid-1940s, she applied the same qualities of ...

    Notes: [Auszug] UNIVERSITY teachers of genetics usually think it necessary to impart a sound knowledge of Mendel's laws, but sometimes fear that spending time on these foundations of the subject will tax the patience of their pupils. First-year students tend to think (even if mistakenly) that they have already ...

    Notes: [Auszug] AT THE level of the DNA sequence, chromosome structure is in a state of constant flux, usually slow but sometimes surprisingly rapid. Many processes sub-versive of conventional genetics have evidently been going on for aeons in the natural world, and over the past several decades descriptions of ...

    Notes: [Auszug] DNA technology is remarkable not only for the great advances in biological knowledge that it has made possible but also for the disagreement and confusion that it has generated in the academic community and among articulate people in general. If any eventual consensus is to be reached we had better ...

    Notes: [Auszug] To explain the almost continuously graded variation seen in derivatives of mutable genes Brink5,6 has proposed that such variation is caused by different numbers of repeated, probably identical self-replicating units associated with the unstable locus. It has not been clear, however, how the ...

Neither of these mutants forms detectable glutamie dehydrogenase, either when grown in medium supplemented with ...
