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).

New Insights Into Ageing Revealed

The way in which blood stem cells evolve over a lifespan differs greatly between humans and mice, new research reveals. The findings provide a new understanding of the critical factors that influence tissue ageing.

Advanced Molecular Tools Help Wildlife Researchers Assess Bat Health

How do wildlife researchers know when an endangered population is sick? They can detect infectious microbes in animal waste, but the presence of a microbe doesn't always equate to impactful symptomatic infections.

New ctDNA Model Enhances Metastatic Cancer Surveillance

In metastatic cancer surveillance, monitoring the actual concentrations of circulating tumor DNA (ctDNA) may be critical. Researchers showed that absolute ctDNA concentration thresholds can be defined to rule out or predict impending cancer progression.

LUC7 Proteins Play Key Role in RNA Splicing Control

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut out and the coding portions are spliced back together.
