Molecular cytogenetics is a combination of molecular biology and cytogenetics. Molecular biology is a subset of biology that is concerned with the molecular basis of biological activity which occurs between biomolecules in numerous systems of a cell. Cytogenetics, on the other hand, is a field of genetics that deals with how the chromosomes are related to cell behavior during mitosis and meiosis. The aim of molecular cytogenetics is to distinguish between normal and cancer-causing cells using various substances. It is a useful tool for diagnosis and treatment of various malignancies like haematological malignancies, brain tumors, etc. It uses the techniques of fluorescent in situ hybridization and comparative genomic hybridization. This book unravels the recent studies in the field of molecular cytogenetics. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. Students, researchers, experts and all associated with molecular cytogenetics will benefit alike from this book.
