【摘要】 Ｚｎ￣（２＋）在遗传调控中的作用十分广泛而显著。结合新近的研究资料，着重从染色质结构与功能、核酸的生物合成、ＤＮＡ的结构及构象、基因表达的调控等四个主要方面来反映Ｚｎ￣（２＋）与遗传调控的相关性，并阐述Ｚｎ￣（２＋）在其中发挥作用的机理。更多还原

【Abstract】 (China).1994:21(6):486-491 The effects of zinc on genetic regulation are ex-tensive and conspicuous.It was shown thatzinc participates in genetic regulation mainlythrough infecting the regulation of gene ex-pression.the structure and function of chro-matin, the conformation of DNA and thebiosynthesis of nucleic acid.The mechanismsof zinc acting in these processes were discussedas well.更多还原
