Dictionary

gene : a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that is the functional unit of inheritance controlling the transmission and expression of one or more traits by specifying the structure of a particular polypeptide and especially a protein or controlling the function of other genetic material — Webster   See also   OneLook

Encyclopedia

Gene is a sequence of DNA or RNA that codes for a molecule that has a function. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism’s offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gene–environment interactions. Some genetic traits are instantly visible, such as eye color or number of limbs, and some are not, such as blood type, risk for specific diseases, or the thousands of basic biochemical processes that constitute life.. — Wikipedia

    on November 18, 2022 at 5:55 pm

    Some dogs have to eat in a high chair—or, more specifically, a Bailey Chair. The chair keeps them in a vertical position while they eat so that gravity can do the work their bodies can't: moving food from the mouth to the stomach.

    As automated facial-expression analysis, or AFEA, becomes increasingly able to recognize facial behavior in everyday life, it will become increasingly important to understand what causes the technology to work incorrectly, as well as anticipate problems that could arise when it does work correctly.

    Genetic studies of the past 20 years have extensively shown how, across human populations worldwide, the majority of genetic differences are encountered at the individual rather than at the population level. Two random humans from a single group tend indeed to be more genetically different from each other than two different human populations on average.

    When humans get hurt, they feel pain. Between these occurrences there is a series of indirect relay reactions. An analogical set called transduction of signals exists in all living organisms, including plants. When a stimulus appears, for instance a draft factor as an attack of a pathogen, a plant receives this information through a receptor, analyzes it, sometimes amplifies it and forms a corresponding reaction.

    Capuchin monkeys (Sapajus spp.) are among only a few primates that use tools in day-to-day activities. In the Cerrado and Caatinga, they use stones as hammers and anvils to crack open cashew nuts, seed pods of Hymenaea courbaril (West Indian locust; jatobá in Brazil) and other hard foods.

  • GATTACA is still pertinent 25 years later

    Nature Genetics, Published online: 24 November 2022; doi:10.1038/s41588-022-01242-5It has been 25 years since the release of GATTACA, a film that tells the story of a credible near future in which society’s inequalities, formerly associated with race and class, have been replaced with new prejudices based on genetic determinism. Here we compare GATTACA’s fictional technologies with reality’s state of the art, assessing the legal protections afforded in today’s society against […]

    Nature Genetics, Published online: 18 November 2022; doi:10.1038/s41588-022-01229-2Few genetic alterations have been linked to metastasis, during which cancer cells acquire abnormal migratory behavior. A new study sheds light on how loss of NECTIN1 leads to melanoma dissemination after local depletion of IGF1.

    Nature Genetics, Published online: 17 November 2022; doi:10.1038/s41588-022-01214-9Expression of mdg4 retrotransposons during Drosophila metamorphosis activates the antiviral NF-κB factor Relish. Silencing of mdg4 or Relish at the pupal stage leads to an inability to clear exogenous viruses in adulthood.
