Macaulay was one of the most versatile, successful, and significant writers in the first half of the twentieth century, Smith a talented but diffident and depressive poet who was briefly an Anglican nun before converting to Roman Catholicism. The letters throw fascinating and often amusing light not only on the writer's private life, unconventional character, and varied career, but also on the lively literary and social circles in which she moved. They are essential reading for all...

Essential Medical Genetics provides students, clinicians, counsellors and scientists with the up-to-date information they need regarding the basic principles underlying medical genetics. It also provides guidance on how to apply current knowledge in clinical contexts, covering a wide variety of topics: from genome structure and function to mutations, screening and risk assessment for inherited disorders.

Epigenetic modifications act on DNA and its packaging proteins, the histones, to regulate genome function. Manifest as the heritable methylation of DNA and as post-translational histone modifications, these molecular flags influence the architecture and integrity of the chromosome, the accessibility of DNA to gene regulatory components and the ability of chromatin to interact within nuclear complexes. While a multicellular individual has only one genome, it has multiple epigenomes reflecting the diversity of cell types and their properties at different times of life; in health and in...
