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).

Scientists detect genomic DNA changes even in sun-protected skin

Researchers have quantified the diverse types of genomic DNA variations that take place in skin cells and found that mutations from UV light is common.

Researchers use heat map data to reverse engineer chromosome models

Genome analysis can provide information on genes and their location on a strand of DNA, but such analysis reveals little about their spatial location in relation to one another within chromosomes -- the highly complex, three-dimensional structures that hold genetic information.

Shell scientist receives prestigious award to develop alternative carbon management technologies

Shell Scientist Christian A. Davies, Ph.D., has been named the recipient of the 2021 Edith and Peter O'Donnell Award in Technology Innovation from TAMEST (The Academy of Medicine, Engineering and Science of Texas). He was chosen for his development of a broad suite of alternative carbon management technologies to reduce emissions for a lower carbon future.

Study reveals richness of space-time gene expression dynamics of the liver

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".

New discovery helps explain how COVID-19 suppresses the body’s immune response

Seeking to understand why COVID-19 is able to suppress the body's immune response, new research from the USC Leonard Davis School of Gerontology suggests that mitochondria are one of the first lines of defense against COVID-19 and identifies key differences in how SARS-CoV-2, the virus that causes COVID-19, interacts with mitochondrial genes when compared to other viruses.

Using proteomics to determine how long a corpse has been underwater

In this interview, AZoLifeSciences speaks to Dr. Noemi Procopio about her latest research which involved using bone proteomics to determine the length of time a corpse had been left underwater.

Scientists trace back evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.

Study addresses mystery of how chromosomes are inherited during cell division

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.

DNA-editing technique used to extend lifespan of mice with progeria

Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy.
