In molecular biology and genetics, DNA annotation or genome annotation is the process of describing the structure and function of the components of a genome, [2] by analyzing and interpreting them in order to extract their biological significance and understand the biological processes in which they participate. [3]
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
These databases collect genome sequences, annotate and analyze them, and provide public access. Some add curation of experimental literature to improve computed annotations. These databases may hold many species genomes, or a single model organism genome.
The Gene Ontology (GO) is a major bioinformatics initiative to unify the representation of gene and gene product attributes across all species. [1] More specifically, the project aims to: 1) maintain and develop its controlled vocabulary of gene and gene product attributes; 2) annotate genes and gene products, and assimilate and disseminate annotation data; and 3) provide tools for easy access ...
Atlas of Genetics and Cytogenetics in Oncology and Haematology; Content; Description: The Atlas is a peer reviewed on-line journal / encyclopedia / database in open access dealing with chromosomes, genes and cancers and the biology of normal and cancerous cells. Data types captured: Annotation on chromosomes, genes and cancers: Organisms: Human ...
Ab Initio gene prediction is an intrinsic method based on gene content and signal detection. Because of the inherent expense and difficulty in obtaining extrinsic evidence for many genes, it is also necessary to resort to ab initio gene finding, in which the genomic DNA sequence alone is systematically searched for certain tell-tale signs of protein-coding genes.
The Vertebrate Genome Annotation (VEGA) database was first made public in 2004 by the Wellcome Trust Sanger Institute. It was designed to view manual annotations of human, mouse and zebrafish genomic sequences, and it is the central cache for genome sequencing centers to deposit their annotation of human chromosomes. [6]
Gene SGCB aligned to the human genome. Central to the Ensembl concept is the ability to automatically generate graphical views of the alignment of genes and other genomic data against a reference genome. These are shown as data tracks, and individual tracks can be turned on and off, allowing the user to customise the display to suit their ...
