Introduction to Genome Biology: Features, Processes, and Structures

Genomic analyses increasingly make use of sophisticated statistical and computational approaches in investigations of genomic function and evolution. Scientists implementing and developing these approaches are often computational scientists, physicists, or mathematicians. This article aims to provide a compact overview of genome biology for these scientists. Thus, the article focuses on providing biological context to the genomic features, processes, and structures analysed by these approaches. Topics covered include (1) differences between eukaryotic and prokaryotic cells; (2) the physical structure of genomes and chromatin; (3) different categories of genomic regions, including those serving as templates for RNA and protein synthesis, regulatory regions, repetitive regions, and “architectural” or “organisational” regions, such as centromeres and telomeres; (4) the cell cycle; (5) an overview of transcription, translation, and protein structure; and (6) a glossary of relevant terms.
