    Details
    ISSN: 1476-4687

    Notes: [Auszug] A WIDE variety of ultra-selfish genetic elements dwell within the genomes of certain organisms - elements which, for instance, disrupt meiosis and distort sex allocation, and generally propagate themselves at a cost to the host genome1. Their distribution has traditionally been considered to be ...

    Sex, slime and selfish genes (1991)
    [s.l.] : Nature Publishing Group
    Nature 354 (1991), S. 23-24 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE initial evolution of sex, meaning the transfer of genetic information and the fusion of gametes, has attracted much less interest than the reasons for maintaining sex. But work by Meland et al.1 and Kawano et al.2 on the genetics of a slime mould provides empirical support ...

    Antibiotics cure asexuality (1990)
    [s.l.] : Nature Publishing Group
    Nature 346 (1990), S. 510-511 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] EGGS contribute cytoplasm to embryos and sperm do not. Extra-nuclear genetic material in males is therefore at an evolutionary dead end. As a consequence, genes in the cytoplasm that cause an egg or embryo to become female will be favoured by selection; for example mitochondrial DNA that finds ...

    Prion infection (1991)
    [s.l.] : Nature Publishing Group

    ISSN: 1476-4687

    Notes: [Auszug] SIR - The finding that the chaperonin heat shock protein 60 (hsp60) catalyses the assembly of further hsp60 molecules1 lends weight to the fascinating possibility2 that prion infection might be due to self-perpetuating protein-directed changes in topology. Although, as both Carlson et al2 and ...

    Notes: [Auszug] THE received orthodoxy1 that animal mitochondrial DNA (mtDNA) is maternally transmitted was given a severe blow a few years ago with the demonstration that in mussels (Mytilus) it apparently comes from both parents . Two reports, by Ski-binski et al.5 and Zouros et ...

    Drunken walk of the diploid (1993)
    [s.l.] : Nature Publishing Group
    Nature 365 (1993), S. 206-207 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] DIPLOIDS typically wend their way to-wards haploidy in a manner reminiscent of drunkards returning from an evening's revelry: one step backwards, two steps forwards. The first step in classical meiosis is to duplicate the chromosomes to pro-duce a tetraploid cell. Two reduction divisions later four ...

    Notes: [Auszug] SIR - Coyne suggests1 that the adaptive divergence of 'ordinary' genes explains reproductive isolation, in particular Hal-dane's rule that unisexual sterility or inviability is limited to the heterogametic sex. Others have proposed that 'novel' genetic phenomena make a large con-tribution to ...

    The uncertain origin of introns (1994)

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] AT first sight introns and sex have little in common, one point apart - for the evolutionary minded, it is not obvious why any organism should have either. If the textbooks1 are to be believed, however, introns are ancient genetic devices that permit exons to be shuffled, so creating new and better ...

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE vast menagerie of early eukaryotes that constitute the Protista is as bizarre an array of the weird and wonderful as can be imagined: from organisms without sex but which nevertheless alternate ploidy, to others that are parasitized by their sister species and almost everything in between. ...

    Notes: [Auszug] PERHAPS more than any other discipline, genetic engineering figures in the public eye in an equivocal light. On the one hand, white-coated geneticists are caricatured as the devoted fighters of cancer and disease but, by equal measure, they could be the cruel experimenters on human ...
