    Description: Transformation, or DNA-mediated gene transfer, permits the introduction of new genetic information into a cell and frequently results in a change in phenotype. The transforming DNA is ultimately integrated into a recipient cell chromosome. No unique chromosomal locations are apparent, different lines contain the transforming DNA on different chromosomes. Expression of transformed genes frequently results in the synthesis of new polypeptide products which restore appropriate mutant cells to the wild-type phenotype. Thus transformation provides an in vivo assay for the functional role of DNA sequence organization about specific genes. Transforming genes coding for selectable functions, such as adenine phosphoribosyltransferase or thymidine kinase, have now been isolated by utilizing transformation in concert with molecular cloning. Finally, transformation may provide a general approach to the analysis of complex heritable phenotypes by permitting the distinction between phenotypic changes without concomitant changes in DNA and functional genetic rearrangements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pellicer, A -- Robins, D -- Wold, B -- Sweet, R -- Jackson, J -- Lowy, I -- Roberts, J M -- Sim, G K -- Silverstein, S -- Axel, R -- CA 16346/CA/NCI NIH HHS/ -- CA 17477/CA/NCI NIH HHS/ -- CA 23767/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1414-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7414320" target="_blank"〉PubMed〈/a〉

    Description: Many eukaryotic genes contain intevening sequences, segments of DNA that interrupt the continuity of the gene. They are removed from RNA transcripts of the gene by a process known as splicing. The intervening sequence in a yeast tyrosine transfer RNA (tRNA Tyr) suppressor gene was deleted in order to test its role in the expression of the gene. The altered gene and its parent were introduced into yeast by transformation. Both genes exhibited suppressor function, showing that the intervening sequence is not absolutely essential for the expression of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wallace, R B -- Johnson, P F -- Tanaka, S -- Schold, M -- Itakura, K -- Abelson, J -- CA10984/CA/NCI NIH HHS/ -- GM 26391/GM/NIGMS NIH HHS/ -- GM 35658/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1396-400.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6997991" target="_blank"〉PubMed〈/a〉

    Description: Several dysgenic traits may occur within the Drosophila melanogaster species as a result of crosses between different strains. Crossing two mutually interacting categories, named inducer and reactive, may lead, among other abnormalities, to a specific kind of female sterility that has proved useful for investigating the genetic factors involved in the interaction. The reactive state appears to result from a cytoplasmic state ultimately controlled by a chromosomal polygenic system. The inducer character is determined by a chromosomal factor that exhibits all characteristics of a transposable element. Overall, the data contribute to clarification of mutator activities in D. melanogaster and open new opportunities to investigate unusual genetic mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bregliano, J C -- Picard, G -- Bucheton, A -- Pelisson, A -- Lavige, J M -- L'Heritier, P -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):606-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766221" target="_blank"〉PubMed〈/a〉

    Description: Nuclear mutations conferring resistance to oligomycin, a mitochondrial inhibitor, shorten the period of the circadian conidiation rhythm of Neurospora crassa from the normal 21.5 hours to 18 to 19 hours and slow the linear growth rate by 30 percent. These olir mutations map very close to frq, a locus at which mutations affecting periodicity have been previously obtained. The possibilities are discussed that mitochondria are involved in circadian rhythm generation and that certain period-length mutations affect mitochondrial functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diekmann, C -- Brody, S -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):896-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6444467" target="_blank"〉PubMed〈/a〉

    Description: Half of the nucleotide substitutions during the evolutionary divergence of genes in animals, bacteria, and viruses are silent changes. These result from an inherent biochemical property of DNA and are fixed by genetic drift. Evolution may be viewed as a device for protecting DNA molecules from extinction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jukes, T H -- New York, N.Y. -- Science. 1980 Nov 28;210(4473):973-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434017" target="_blank"〉PubMed〈/a〉
