Growth factors as transforming proteinsrally and functionally characterized, including cloning of their cDNAs (Table 1). The total number of polypeptide growth, factors is likely to be considerably higher, since additional factors, that have not yet been fully characterized, are known from their specific biological activities. There are

A chromosomal basis of lymphoid malignancy in manenic determinants. Accordingly, variability is required in that part of the molecule which recognises and binds to antigen, whereas constant functions (effector functions) are necessary as well. This dual requirement is met by the genes which encode the various receptor proteins: each of the loci, i

The nucleoskeleton and the topology of transcriptionentirely from material prepared using hypotonic salt concentrations. Studies on subnuclear structures isolated using hypertonic conditions, and more recently using conditions closer to the physiological, suggest an alternative. Transcription occurs as the template moves past a polymerase attached to

Wessex, Elusive and Independent,and gradually developed into a novel paradigm of modern science and technology. Over the past decade, there have been a great number of new discoveries and results reported in this exciting area, and metamaterials/metasurfaces have led to a myriad of new engineering applications. This chapter introd
