DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Genetic testing advances help to uncover primary immune deficiency diseases

Infections caused by primary immunodeficiency diseases (PID) can be persistent and life-threatening. More than 450 PIDs have been identified, yet diagnosing them quickly and accurately remains a difficulty.

Researchers use gene-editing in tomatoes to boost vitamin D content

Researchers employed gene editing to switch off a specific component in the tomato plant’s DNA, which led to an increase in provitamin D3 in both the fruit and leaves. After that, UVB light was used to convert it to vitamin D3.

Study uncovers how CD8+ T cells can divide and produce two distinct daughter cells

An immunological problem has been addressed by scientists at St. Jude Children’s Research Hospital. Despite being genetically identical, a CD8+ T cell can divide and produce two functionally different daughter cells.

Researchers take a deep dive into the genetic origins of mustelid physiological and behavioral range

Within the order Carnivora, Mustelids are the most ecologically and taxonomically varied family. They inhabit a range of natural niches, from the tayra in the tropics to the wolverine in the subarctic, and have developed species-specific features relating to their feeding, reproductive strategy, and shape.

Study shows polymersome can effectively deliver PARP1 siRNA to treat breast cancer

Small interfering RNAs, or siRNAs, have the potential to cure tumors by targeting knocking down oncogenes that drive tumor development while avoiding the damage associated with chemotherapy.

Research shows how visible hotspots may be easy to target with immune-stimulating drugs

Many cancers include genetic “hotspots,” or sections of DNA that are subject to mutation. For example, a mutation in the TP53 gene is found in more than 50% of all cancers, generally within a narrow DNA range.
