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 identifies the gene responsible for toxic vicine and convicine production in faba beans

Faba beans have been a good source of protein. A team of experts has now found the gene that causes the toxic vicine and convicine to be produced.

Making memories necessitates a lot of DNA breakage

The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations--more than previously realized, according to a new study--to provide quick access to genetic instructions for the mechanisms of memory storage.

Researchers uncover cellular mechanisms by which the silencing therapies act in cells

Gene silencing therapies are used to interfere with, or "silence", the expression of genes that are associated with disorders. Now, a team at TMDU has uncovered some of the cellular mechanisms by which the silencing therapies act in cells.

New method yields 10 times more accessible details of gene activity in individual cells

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types.

Epstein-Barr virus reactivation likely to blame for long COVID symptoms

Long COVID symptoms, such as weariness, brain fog, and rashes, may be caused by Epstein-Barr virus (EBV) reactivation because of the inflammatory response to coronavirus infection, which occurs in about 30% of individuals following recovery from initial COVID-19 infection.

Study reveals how cells “read” synthetic ingredients added to a genetic code

If the genome is considered the recipe for life, then base pairs represent the individual ingredients. DNA is made up of these chemical structures, and every living thing on the planet has just four of them.
