Abstract

Bacteriophage T4 deoxyribonucleic acid (DNA)-protein complexes were retained preferentially on glass fiber filters. DNA polymerase activity in the complex was detected through the incorporation of (3)H-labeled DNA precursors. The primer-product DNA hybridized with both phage and Escherichia coli DNA. Density labeling experiments showed that about 30% of incorporated (3)H-deoxyadenosine triphosphate was found in DNA which hybridized with phage DNA; this DNA was found to be covalently attached to the primer DNA.

摘要

噬菌体T4脱氧核糖核酸(DNA)-蛋白质复合物优先保留在玻璃纤维滤膜上。通过掺入(3)H标记的DNA前体来检测复合物中的DNA聚合酶活性。引物-产物DNA与噬菌体和大肠杆菌DNA均杂交。密度标记实验表明,在与噬菌体DNA杂交的DNA中发现约30%掺入的(3)H-脱氧三磷酸腺苷;发现该DNA与引物DNA共价连接。
