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).

Cellular senescence variations may help control health and onset of age-related diseases

Researchers from Kumamoto University, Japan have proposed that cellular senescence variations during the aging process could lead to control of health and onset of age-related diseases.

Exploiting CRISPR systems for the fast detection of SARS-CoV-2

A paper published on medRxiv describes a repurposed type III CRISPR-Cas system that can detect the virus from nasopharyngeal swabs in less than an hour.

Study shows how genetic variability may shape mathematical performance in children

According to a study, DNA variation in a gene is linked to early anatomical variations in a region of the brain that plays a crucial role in quantity representation.

Scientists explain the role of transcription factors in genetic diseases

Transcription factor proteins can be described as the light switches of the human genome. These proteins bind to DNA and allow genes to turn “on” or “off.”

New DNA-cutting tool could advance gene editing for novel treatments

Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger pieces of DNA out of a cell's genome, according to a new study by UC San Francisco scientists.

Researchers discover how specific molecules promote cancer progression

The development of cancer is a highly complicated process, involving multiple genes and signaling pathways that become upregulated or downregulated throughout different stages of tumor growth and spread. Two of the most commonly altered genes in cancer are p53 and AKT.
