Lyudmila Nezhelskaya,Diana Tumashkinaht provide clues in our studies of cancer etiology or developmental biology. One of the most notable was the dis covery of reverse transcriptase. This marked a momentous occasion in the history of molecular biology. Not only did it provide insight into the mechanism of persistence of retroviruses b

Gurami Tsitsiashvili,Marina Osipovars that geographic differences exist. Epizootiologic and transmission studies performed in the past suggested an infectious agent of the disease, and a virus was considered as the main candidate. Progress supporting this view has been made during recent years in research on type C tumor viruses that

Dmitry Efrosinin,Irina Gudkova,Natalia Stepanovaly inherited in the extrachromosomal (autonomous) state. The plasmids of entero-bacteria can be divided into two distinct groups according to their size: (i) small plasmids with MW of less than 10 Mdal, and (ii) large plasmids with MW ranging from 50–100 Mdal. These two groups differ strikingly in t

Andrei V. Zoriney can be induced against many, although by no means all, experimentally induced animal tumors when transplanted into syngeneic hosts (. and ., 1969b; ., 1965; ., 1973). This was originally established in tests with animal tumors, either induced by chemical carcinogens or oncogenic viruses, or arisin
