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

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

Science

Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. — Wikipedia

Encyclopædia Britannica


Genomics is an interdisciplinary field of science focusing on the structure, function, evolution, mapping, and editing of genomes. A genome is an organism’s complete set of DNA, including all of its genes. In contrast to genetics, which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of genes, which direct the production of proteins with the assistance of enzymes and messenger molecules. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genomics also involves the sequencing and analysis of genomes through uses of high throughput DNA sequencing and bioinformatics to assemble and analyze the function and structure of entire genomes.[Advances in genomics have triggered a revolution in discovery-based research and systems biology to facilitate understanding of even the most complex biological systems such as the brain. — Wikipedia

Nature Genetics - Issue - nature.com science feeds Nature Genetics publishes the very highest quality research in genetics. It encompasses genetic and functional genomic studies on human traits and on other model organisms, including mouse, fly, nematode and yeast. Current emphasis is on the genetic basis for common and complex diseases and on the functional mechanism, architecture and evolution of gene networks, studied by experimental perturbation.

    Nature Genetics, Published online: 29 November 2019; doi:10.1038/s41588-019-0553-1As the year comes to a close and we start to look ahead to 2020, we thought that we would highlight some of our favorite Nature Genetics papers from 2019. This snapshot also captures some of the topics and themes in genetics that we are most excited to see develop in the near future.

    Nature Genetics, Published online: 29 November 2019; doi:10.1038/s41588-019-0540-6A new study presents a powerful experimental approach, CRISPRi-FlowFISH, for mapping regulatory interactions, and uses it to characterize thousands of putative enhancer–gene pairs. The results suggest that most current approaches for predicting enhancer–gene interactions perform poorly, but a simple mathematical model combining distance with enhancer activity shows promise.

    on December 13, 2019 at 7:34 pm

    Growing up in the wild makes plants tough. Wild plants evolve to survive the whims of nature and thrive in difficult conditions, including extreme climate conditions, poor soils, and pests and disease. Their better-known descendants—the domesticated plants that are critical to a healthy diet—are often not nearly as hardy. The genes that make crop wild relatives robust have the potential to make their cultivated cousins—our food plants—better prepared for a harsh climate […]

    Agricultural chemists from RUDN University have developed a new way to deal with cleavers, a weed that is the main enemy of winter wheat crops. They found a combination of herbicides that, as the experiments have shown, increases the yield of winter wheat by 46-60 percent. The results are published in Archives of Agronomy and Soil Science.
