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).

Study shows how telomeres protect chromosome ends

Telomeres are essentially specialized structures that are located at the end of chromosomes. These structures ensure a healthy cell division.

A non-physical method for generating random building blocks

True random numbers are required in fields as diverse as slot machines and data encryption. These numbers need to be truly random, such that they cannot even be predicted by people with detailed knowledge of the method used to generate them.

Endogenous viral elements play important role in genome evolution of green algae

Viruses are tiny invaders that cause a wide range of diseases, from rabies to tomato spotted wilt virus and, most recently, COVID-19 in humans. But viruses can do more than elicit sickness -- and not all viruses are tiny.

Somatic mutation acts as natural gene therapy in patients with GATA2 deficiency

Researchers affiliated with the Center for Cell-Based Therapy (CTC) in Ribeirão Preto, Brazil, have identified for the first time a non-hereditary mutation in blood cells from a patient with GATA2 deficiency, a rare autosomal disease caused by inherited mutations in the gene that encodes GATA-binding protein 2 (GATA2).
