|Annotation||The process of attaching additional information to biological entities. Annotation can be structural (i.e. identification of the elements from a sequence, such as protein coding regions or the location of regulatory motifs) or functional (i.e. adding biological information to the identified elements, such as the biological function of a protein domain or an entire protein, or the molecular interactions or regulatory role of a nucleotide sequence). Annotation can either be applied automatically or can be manually added (in a process called 'curation') from various sources, such as the scientific literature. At EMBL-EBI, we use a combination of automatic and manual annotation to enrich our databases. Annotation can either be applied automatically or it can be curated (manually) from the scientific literature. At EMBL-EBI, we use a combination of automatic and manual annotation to enrich our databases. |
|ArrayExpress||ArrayExpress is a database of functional genomics experiments that can be queried and the data downloaded. www.ebi.ac.uk/arrayexpress/ |
|Expression Atlas||Expression Atlas provides information on gene expression patterns under different biological conditions. |
|gene||A molecular unit of heredity of a living organism. Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring. All organisms have many genes corresponding to various biological traits, some of which are immediately visible, such as eye color or number of limbs, and some of which are not, such as blood type or increased risk for specific diseases, or the thousands of basic biochemical processes that comprise life. |
|gene expression||The process by which information from a gene is used in the synthesis of a functional product. Gene expression is the most fundamental level at which the genotype gives rise to the phenotype. The genetic code stored in DNA is "interpreted" by gene expression, and the properties of the expression give rise to the organism's phenotype.
