DNA News and Research

RSS

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).

The First Parent-Of-Origin Gene Atlas of The Mammary Gland

This study maps dynamic gene expression in mouse mammary glands, revealing insights into lactation, maternal health, and breast cancer risk through imprinting.

Loss of Zfy Genes Explains Why Some Sperm Fail

A study at the University of Hawaiʻi at Mānoa by researchers from the John A. Burns School of Medicine (JABSOM) found that losing a crucial male fertility gene causes infertility and alters the expression of hundreds of other genes.

Soil DNA Reveals Hundreds of Unknown Bacterial Genomes

Most bacteria cannot be cultured in the lab-and that's been bad news for medicine. Many of our frontline antibiotics originated from microbes, yet as antibiotic resistance spreads and drug pipelines run dry, the soil beneath our feet has a vast hidden reservoir of untapped lifesaving compounds.

spVelo: A New Method for Integrating Spatial and Temporal Data in RNA Velocity Analysis

Essentially all cells in an organism's body have the same genetic blueprint, or genome, but the set of genes that are actively expressed at any given time in a cell determines what type of cell it will be and its function.

Discovery of De Novo Genes Sheds Light on Peach Evolution and Traits

The emergence of new genes is a central driver of evolutionary innovation. While mechanisms such as duplication and horizontal gene transfer have been widely studied, de novo gene birth represents a unique pathway where functional genes arise from noncoding DNA.
