The structures of Borg genomes are conserved and distinct from the plasmids and chromosomes of Methanoperedens, as well as other archaeal genomes. [4] Borgs do not contain protein-coding genes that are associated with plasmids or viruses; they also lack rRNA genes, origins of replication, or other vital genes and features that are commonly found within minichromosomes (also known as ...
While there are significant differences among the genomes of human individuals (on the order of 0.1% due to single-nucleotide variants [9] and 0.6% when considering indels), [10] these are considerably smaller than the differences between humans and their closest living relatives, the bonobos and chimpanzees (~1.1% fixed single-nucleotide ...
The first printout of the human reference genome presented as a series of books, displayed at the Wellcome Collection, London. A reference genome (also known as a reference assembly) is a digital nucleic acid sequence database, assembled by scientists as a representative example of the set of genes in one idealized individual organism of a species.

Distinct from the PANGOLIN tool, Pango lineages are regularly, manually curated based on the current globally circulating diversity. A large phylogenetic tree is constructed from an alignment containing publicly available SARS-CoV-2 genomes, and sub-clusters of sequences in this tree are manually examined and cross-referenced against epidemiological information to designate new lineages; these ...
Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing.
The advent of complete genomes in the 1990s (the first one being the genome of Haemophilus influenzae sequenced in 1995) introduced a second generation of annotators. Just like in the previous generation, they performed annotation through ab initio methods, but now applied on a genome-wide scale.
In contrast, to the relatively faster unconstrained DNA half-life (2.5–14 my) of the plant and insect genomes, the mammalian DNA half-life is estimated to be much slower (884 my) which along with the minimal requirements of Helitron transposition and the slow rate of decay in mammals have caused this pattern of vertical persistence.
