    Cloning human fetal gamma globin and mouse alpha-type globin DNA: preparation and screening of shotgun collections (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-12-22
    Description: Shotgun collections of Charon 3A bacteriophages containing Eco RI fragments of human and mouse DNA were constructed with the use of in vitro packaging. Plaques were screened by hybridization, and globin-specific clones were isolated from both human (Charon 3AHs51.1) and mouse (Charon 3AMm30.5). The fragments cloned were detected in unfractionated genomic DNA by the Southern method of hybridization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blattner, F R -- Blechl, A E -- Denniston-Thompson, K -- Faber, H E -- Richards, J E -- Slightom, J L -- Tucker, P W -- Smithies, O -- New York, N.Y. -- Science. 1978 Dec 22;202(4374):1279-84.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/725603" target="_blank"〉PubMed〈/a〉

    Cloning human fetal gamma globin and mouse alpha-type globin DNA: characterization and partial sequencing (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-12-22
    Description: Two globin-related clones isolated from collections of bacteriophages containing unfractionated Eco RI fragments of human and mouse DNA were characterized. Charon3AHs51.1Hbgamma includes 2.7 kilobase pairs of human DNA containing a large part of a fetal gamma globin chain structural gene; Charon 3AMm30.5 includes 4.7 kilobase pairs of mouse DNA related to alpha globin. The human fetal gamma globin gene has within its coding region two intervening sequences of noncoding DNA, IVS 1 and IVS 2, of approximately 1-0 and 900 base pairs. Sequence IVS 1 is located at the position of one of the two intervening sequences occurring in adult globin genes; IVS 2 is located at the position of the other.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smithies, O -- Blechl, A E -- Denniston-Thompson, K -- Newell, N -- Richards, J E -- Slightom, J L -- Tucker, P W -- Blattner, F R -- New York, N.Y. -- Science. 1978 Dec 22;202(4374):1284-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/725604" target="_blank"〉PubMed〈/a〉

    The detection of mitotic and meiotic aneuploidy in yeast using a gene dosage selection system (1988)

    Notes: Summary A system is described in which spontaneous and chemically-induced mitotic and meiotic hyperploidy can be assayed in the same diploid culture of Saccharomyces cerevisiae. Monitoring gene dosage changes at two loci on chromosome VIII, the test utilizes a leaky temperature-sensitive allele arg4-8 and low level copper resistance conferred by the single copy allele cup1 s. An extra chromosome VIII provides simultaneous increased dosage for both genes, resulting in colonies that are both prototrophic for arginine at 30° C and copper resistant. During mitotic cell divisions in diploids, spontaneous chromosome VIII hyperploids (trisomes and tetrasomes) occur at a frequency of 6.4×10-6 per viable cell. Among ascospores, the spontaneous chromosome VIII disome frequency is 5.5×10-6 per viable spore. The tubulin-binding reagent methyl benzimidazol-2-yl carbamate (MBC) elicits enhanced levels of mitotic and meiotic aneuploidy relative to control levels. The system represents a novel model for examining chromosome behavior during mitosis and meiosis and provides a sensitive and quantifiable procedure for examining chemically induced aneuploidy.
