Viruses, being obligatory parasites of their host cells, rely on a vast supply of cellular components for their replication, regardless of whether infection leads to cell death or to the state of persistence. Animal viruses are providing scientists with relatively simple models to study the molecular biology of genome replication and gene expression. Whereas viruses use, in general, pathways of macromolecular biosynthesis common to the host cell, they have a cunning ability to adopt unusual mechanisms of gene expression and gene replication, provided these special pathways offer an advantage...

The synthesis of proteins by ribosomes is a fundamental cellular process. Cells must tightly control protein synthesis to maintain homeostasis and regulate proliferation, growth, differentiation, and development. Indeed, aberrant translational control is associated with cancer, several neurologic syndromes, and genetic disorders including -ribosomopathies.- Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers our current understanding of protein synthesis and its control, from the genomic level to single- molecule analysis and...
