Reference genome

, London A reference genome is a genome assembly that represents the complete genetic sequence of an organism as a continuous string of nucleotides (A, T, C, and G). For an assembly to serve as a reference genome, it is typically accompanied by annotations, produced through a process known as DNA or genome annotation. The annotations specify the genomic coordinates (start and end locations) of genes, exons, introns, and mRNA, and are often paired with corresponding transcript (mRNA) and protein sequences (algorithm predicted or experimentally validated). Reference genomes exist for a wide variety of species, including species of viruses, bacteria, fungi, plants and animals, and they differ in how they are constructed and represented. A reference may be derived from a single individual or from multiple individuals whose sequences are collapsed into one representative assembly - haplotype. Two main factors determine reference genome's assembly quality: the sequencing technology which affects sequence accuracy and the assembly level which indicates how complete the genome representation is. The ideal is a chromosome-level assembly, which is a complete DNA sequence for each chromosome with no unplaced segments. However, achieving this remains technically challenging, especially for large or repetitive genomes (dense in repetitive elements).…
