DNA is naturally composed of four basic molecules called nucleotides (commonly known as ‘letters’) — A (adenine), T (thymine), C (cytosine) and G (guanine) — that form hydrogen bonds in order to pair. A research team led by Dr. Steven Benner of the Foundation for Applied Molecular Evolution added an …

A global group of researchers from the USA and also Europe has actually efficiently sequenced the genome of the terrific white shark (Carcharodon carcharias )as well as contrasted it to the genomes from a range of various other animals.

A group of researchers from the Oregon National Primate Research Center at Oregon Health as well as Sciences University has actually discovered that a genetics called the G-protein combined receptor 39 (GPR39 )had reduced expression in the minds of nonhuman primates that willingly eaten hefty quantities of alcohol compared to …

An international team of scientists has sequenced and analyzed the genomes of representatives from all five major clades within the birds-of-paradise family (Paradisaeidae): the paradise crow (Lycocorax pyrrhopterus) from Obi Island in Indonesia, the paradise riflebird (Ptiloris paradiseus) from New South Wales, Australia, the huon astrapia (Astrapia rothschildi), the King …

An international team of researchers led by a University of Liverpool scientist has discovered three new genes associated with increased risk of age-related macular degeneration, the most common cause of blindness in the elderly. Dry age-related macular degeneration is one of the most common causes of vision loss in people …

A research team led by Florida State University scientists has demonstrated that there are specific points along the DNA molecule that control replication. The study appears in the journal Cell. Sima et al found that cis-regulatory elements control the 3D compartmentalization, architecture of the genome, and replication timing in a …

A research team led by Rockefeller University scientists has discovered a genetic variant that makes people more vulnerable to tuberculosis, a disease caused by the bacterium Mycobacterium tuberculosis. The team also uncovered genetic mutations that rob the immune system of its ability to combat more ubiquitous germs of the same …

Researchers have for the first time mapped the genome of the Himalayan marmot (Marmota himalayana), a hibernating mammal that inhabits the high-elevation regions of the Himalayan mountains. Published in the journal iScience, the results hint at the genetic mechanisms underlying high-altitude adaptation and hibernation. The Himalayan marmot (Marmota himalayana). Image …

A team of scientists at the University of Washington has genetically modified a common houseplant, the pothos ivy (Epipremnum aureum), to efficiently remove two toxins — chloroform and benzene — from the air around it. The transgenic plant expresses a protein that transforms toxins into molecules that the plant can …
