    Similar amino acid sequences: chance or common ancestry? (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-10-09
    Description: The systemic comparison of every newly determined amino acid sequence with all other known sequences may allow a complete reconstruction of the evolutionary events leading to contemporary proteins. But sometimes the surviving similarities are so vague that even computer-based sequence comparisons procedures are unable to validate relationships. In other cases similar sequences may appear in totally alien proteins as a result of mere chance or, occasionally, by the convergent evolution of sequences with special properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doolittle, R F -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):149-59.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280687" target="_blank"〉PubMed〈/a〉

    Diameter of the cell-to-cell junctional membrane channels as probed with neutral molecules (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-31
    Description: The cell-to-cell channels in the junctions of an insect salivary gland and of insect and mammalian cells in culture were probed with fluorescent molecules-neutral linear oligosaccharides, neutral branched glycopeptides, and charged linear peptides. From the molecular dimensions of the largest permeants and smallest impermeants the permeation-limiting channel diameter was obtained: 16 to 20 angstroms for the mammalian cells and 20 to 30 angstroms for the insect cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwarzmann, G -- Wiegandt, H -- Rose, B -- Zimmerman, A -- Ben-Haim, D -- Loewenstein, W R -- CA 14464/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):551-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244653" target="_blank"〉PubMed〈/a〉

    Left-handed double helical DNA: variations in the backbone conformation (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-01-09
    Description: Four different crystals of d(CpGpCpGpCpG) have been solved by x-ray diffraction analysis and all form similar left-handed double helical Z-DNA molecules in the crystal lattice. Two different conformations are observed for the phosphates in the GpC sequences, as the phosphates are found either facing the helical groove or rotated away from it. The latter conformation is often found when hydrated magnesium ions are complexed to a phosphate oxygen atom. These different conformations may be used when right-handed B-DNA joins left-handed Z-DNA. Atomic coordinates and torsion angles are presented for both types of Z-DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, A J -- Quigley, G J -- Kolpak, F J -- van der Marel, G -- van Boom, J H -- Rich, A -- New York, N.Y. -- Science. 1981 Jan 9;211(4478):171-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444458" target="_blank"〉PubMed〈/a〉

    The evolution of cooperation (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-03-27
    Description: Cooperation in organisms, whether bacteria or primates, has been a difficulty for evolutionary theory since Darwin. On the assumption that interactions between pairs of individuals occur on a probabilistic basis, a model is developed based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game. Deductions from the model, and the results of a computer tournament show how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established. Potential applications include specific aspects of territoriality, mating, and disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Axelrod, R -- Hamilton, W D -- New York, N.Y. -- Science. 1981 Mar 27;211(4489):1390-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466396" target="_blank"〉PubMed〈/a〉

    Publication Date: 1981-01-16
    Description: Models of deoxyribonucleic acid (DNA) having chain directions opposite to those of the Watson and Crick model offer strikingly different alternatives for DNA structures. Satisfactory models of the B and C forms of DNA have been built. Left-handed models readily form by twisting right-handed ones, and models can be bent into tight supercoils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hopkins, R C -- New York, N.Y. -- Science. 1981 Jan 16;211(4479):289-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444467" target="_blank"〉PubMed〈/a〉
