...second edition contains a few surprises. A lot has happened in molecular biology in the last five years, and most of the changes are reflected in comparison of the two editions. Substantial amounts of new information have accumulated in diverse areas: In the 1965 edition, Watson ended a chapter with the announcement that "much more must be learned about ribosomes." In the 1970 edition, there are twenty pages of new information. There is also new information on specific genetic mutagens, enzymes for genetic mutagens, enzymes for genetic recombination, specific factors to start and stop RNA transcription, new known gene codes...
...replication and DNA and RNA viruses are sure to attract some attention. Students who took Nat Sci 5 or Bio 2 or any other introductory biology course before this year and think they learned about DNA replication in those classes will be surprised by Watson's new chapter on DNA duplication. DNA replication is often presented as the unwinding and subsequent rewinding of linear complementary ploy-nucleotide strands of DNA. However, this chapter now offers the Rolling Circle model of DNA replication, a complex model of revolving, duplicating circular DNA strands. Evidence is also given for the transition from linear...
...Rolling Circle idea is not the only mystery presented in this chapter. During the summer experiments were made that indicated that the polymerize enzyme researchers have been using to replicate DNA in the test tube may not be the same one living cells actually use. Watson's late publishing date enabled him to add some general comments on this evidence...
...will finish three books, if God grants me life." The Renewal, Volume I of the projected three-volume Memoirs of Hope, appeared six weeks ahead of schedule in October, and immediately became the fastest seller in French publishing history. Last week De Gaulle was working on the third chapter of the second book, which was due to be published late next year. As usual, he dictated to his secretary from notes, frequently staring out the window at La Boisserie's ancient trees while searching for details in his prodigious memory. In the late afternoon, he looked over the typewritten...
...years ago, Kent's black students and S.D.S. members staged a sit-in to protest recruiters from the Oakland. Calif., police department. White branded the action "intolerable." In the spring of 1969. he suspended officers of the S.D.S. chapter. When angry students responded by occupying a building, police made 58 arrests. Before any of the accused were tried, White suspended them without a hearing...
