The Xenotext is an ongoing work of BioArt by experimental Canadian poet Christian Bök.The primary goal of the project is twofold: first, a poem, encoded as a strand of DNA, is implanted into the bacterium Deinococcus radiodurans; second, the bacterium reads this strand of DNA and produces a protein which is also an intelligible poem.
The European Nucleotide Archive (ENA) is a repository providing free and unrestricted access to annotated DNA and RNA sequences. It also stores complementary information such as experimental procedures, details of sequence assembly and other metadata related to sequencing projects. [1]
The term "repeated sequence" was first used by Roy John Britten and D. E. Kohne in 1968; they found out that more than half of the eukaryotic genomes were repetitive DNA through their experiments on reassociation of DNA. [5] Although the repetitive DNA sequences were conserved and ubiquitous, their biological role was yet unknown.
DNA sequencing is the process of determining the nucleotide sequence of a given DNA fragment. The sequence of the DNA of a living thing encodes the necessary information for that living thing to survive and reproduce. Therefore, determining the sequence is useful in fundamental research into why and how organisms live, as well as in applied ...
Many LCRs are concentrated in "hotspots", such as the 17p11-12 region, 27% of which is composed of LCR sequence. NAHR and non-homologous end joining (NHEJ) within this region are responsible for a wide range of disorders, including Charcot–Marie–Tooth syndrome type 1A , [ 5 ] hereditary neuropathy with liability to pressure palsies , [ 5 ...
Whereas Y-DNA and mtDNA haplogroups represent but a small component of a person's DNA pool, autosomal DNA has the advantage of containing hundreds of thousands of examinable genetic loci, thus giving a more complete picture of genetic composition. Descent relationships can only be determined on a statistical basis, because autosomal DNA ...
In 2012, the sequencing of 1092 genomes was announced in a Nature publication. [2] In 2015, two papers in Nature reported results and the completion of the project and opportunities for future research. [3] [4] Many rare variations, restricted to closely related groups, were identified, and eight structural-variation classes were analyzed. [5]
Silencers are DNA sequences found in the 5′ flanking region of eukaryotic genes, assisting in the silencing of a gene. They can be found upstream, downstream, or within the gene of interest. [ 3 ] When repressors bind silencers, they act in a similar fashion as enhancers and bend over to prevent the interaction of RNA polymerase with promoters.
