    Notes: [Auszug] SIR - I am a recent PhD graduate, and Nature's manifesto for British science (Nature 353, 105; 1991) does not relieve my fears about the long-term prospects in science and technology and the likelihood of permanent employment in Britain for myself and my peers. Young people are ...

    Notes: [Auszug] An unusual protein splicing reaction joins the N-terminal segment (A) and the C-terminal segment (C) of the 119K primary translation product (ABC) of the yeast VMA1 gene to yield a 69K vacuolar H+-ATPase subunit (AC) and an internal 50K polypeptide (B). This 50K protein is a ...

    Notes: [Auszug] INITIATION of chromosomal DNA replication, which defines the transition from the Gl to the S phase of the cell cycle, is a pivotal event in the life of a eukaryotic cell. It occurs with precise timing and is carefully coordinated with other events in the cell cycle. Moreover, S phase is normally ...
