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).

Ancestry-Specific Genetic Models Advance Breast Cancer Risk Assessment

Despite major advances in genetic testing for breast cancer risk prediction, death rates remain disproportionately high among women of African ancestry.

Genome Shock Breaks Reproductive Barriers in Plant Hybrids

In the plant world, when two different species mate, their offspring often don't survive. The reason lies in their DNA: incompatible genes often mix in their offspring, triggering a fatal breakdown known as hybrid lethality that acts as a reproductive barrier to keep species separate.

Novel RNA Molecule Preserves Cell Structure, Impacts Cancer Survival

In a recent study published in the Proceedings of the National Academy of Sciences (PNAS), researchers at the Texas A&M University Health Science Center (Texas A&M Health) identify a novel RNA molecule that plays a crucial role in preserving the integrity of a key cellular structure, nucleolus (a dense region of the cell containing a subset of crucial genetic material).

New Research Reveals RFC's Dynamic Partnership in DNA Synthesis

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands.

How DNA Leakage into the Cytoplasm Drives Ruijs-Aalfs Syndrome

Although DNA is tightly packed and safeguarded within the cell nucleus, it remains continually at risk of damage from normal metabolic activity and external stressors such as radiation and chemical agents.

Defective DNA Protein Repair Triggers Inflammation and Premature Aging

Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature aging and embryonic lethality in mice.

Cryo-EM Uncovers Alarmone-Driven RNA Transcription Initiation

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) into ribonucleic acid (RNA) can be initiated.

Abundance of Oral Microbes Is Strongly Influenced by Genetics

No matter how much they brush their teeth, some people still get more cavities than others, in part because of differences in genetics and the make-up of the microbes in their mouths.
