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).

Bacteria Have Complex Circadian Clocks, Study Finds

Bacteria make up more than 10% of all living things but until recently we had little realization that, as in humans, soil bacteria have internal clocks that synchronize their activities with the 24-hour cycles of day and night on Earth.

New Nanopore Technology Can Identify Single-Molecule Protein Variations

A group of researchers guided by the University of Oxford has made significant progress in detecting changes in protein structures. The method, which was published in Nature Nanotechnology, uses novel nanopore technology to detect structural variations at the single-molecule level, even deep within long protein chains.

Analyzing DNA Damage-Induced NF-κB Targeted by Novel Small Molecule Inhibitors

Chemotherapy and radiotherapy aim to destroy cancer cells by inducing DNA double-strand breaks – damage that, once inflicted, usually causes the cells to die. But damage to a cell's genetic material also activates a signaling pathway called IKK/NF-κB that helps prevent cell death, thus limiting the success of these treatments in patients.

New Method Facilitates Early Detection and Localization of Tumors

To help with early tumor diagnosis and tumor localization, researchers have devised a technology that concurrently detects many cancer-specific DNA circulating hallmarks.

Breakthrough in Single-Cell Genome Sequencing: New Method Reduces Bias and Expands Research Horizons

It has long been technically difficult to sequence the genome of a single bacterial cell due to the nearly impossible bias in the gene amplification stage of the process, making it difficult to produce a high-coverage genome sequence from precisely one bacterial cell.
