    Notizen: [Auszug] IN the last few years chromosome studies have made great progress both in theory and in methods. These methods are, however, little known outside genetical laboratories. The application to human chromosome studies of the techniques developed in cytological laboratories has been a ...

    Notizen: [Auszug] AUERBACH1,2,3,4 reported that the exposure of adult males to the vapours of allyl isothiocyanate increases the mutation-rate in Drosophila melano-gaster. About a fifth of the lethals thus produced were found by Slizynska and Slizynski5 to be connected with ...

    Notizen: [Auszug] Kodani, Calvin and Goldschmidt1 and Kodani published a series of papers in which they describe the action of various sodium hydroxide and urea solutions on salivary gland chromosomes. The first steps on the reaction are the breaking up of bands into discrete granules, followed by ...

    Notizen: [Auszug] WE are grateful for the opportunity of replying to Dr. Bateman's criticism. (1) The main and most pertinent of his objections is levelled against the small scale of our experiment. We fully agree with him on this point. We thought we had made this clear when we described our work as a "pilot ...

    Notizen: [Auszug] This last point is of particular significance for estimates of radiation damage in man. In a human population exposed to chronic irradiation, spermatogonia form the majority of treated cells, and it is their sensitivity which in the main determines the genetical effectiveness of the exposure. As ...

    Notizen: [Auszug] The first part of the meiotic prophase, always visible between 24 and 48 hr. after birth, starts with leptotene and passes through zygotene and pachytene. These stages can be easily seen in squash preparations of the whole ovaries. The beginning of the dictyotene stage is marked by the appearance ...

    Notizen: [Auszug] Fig. 1. Squash preparations of mouse testis. For explanation see text. The two micrographs show variation in the size of the chromosomes and in the intensity of their staining in squash preparations of mouse testis. Fig. la shows three neighbouring metaphase plates of the first meiotic division. ...

    Notizen: [Auszug] IN 1927, Muller showed that X-rays and radium can produce mutational changes. In a continuation of this work on irradiation, I have observed changes in chromosomal number in accordance with findings of other investigators. It may be mentioned that the cells of tumour tissues usually have ...

    Notizen: [Auszug] The study of chromosome morphology in meiotic prophase may perhaps open up some possibility in this direction. Mapping of human chromosomes in the pachytene stage of the spermatocyte is probably only a matter of time, and it is probable that in the near future there will be available a satisfactory ...
