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).

Plant Response to Elevated Carbon Dioxide is Transgenerational and Orchestrated by DNA Methylation

New research lead by Keith Slotkin, PhD, member, Donald Danforth Plant Science Center opens the door for scientists to equip plants with the tools they need to adapt to rising levels of carbon dioxide (CO2), high heat, and other stressors associated with climate change.

New Epigenetic Vulnerability Of Acute Myeloid Leukemia Revealed

Acute myeloid leukemia (AML) is an aggressive blood cancer that causes uncontrolled accumulation of white blood cells. Because of the poor outcomes of this disease, researchers across the globe have been on the hunt for new ways to treat AML, while preserving normal blood development.

The Modified Development Potential of Worm Embryonic Cells

A startling discovery that challenges the conventional wisdom that the majority of the hereditary information for cell differentiation is encoded within DNA and other genetic factors has been made regarding how specific proteins within the chromosomes of roundworms facilitate their offspring to develop specialized cells generations later.

Attacking the HTLV-1 Virus With the Help of Special Gene Scissors

HTLV-1 triggers aggressive forms of leukemia or an incurable spinal cord disease that leads to paralysis: the virus is the often ignored but no less insidious sibling of the HIV virus that causes AIDS and also belongs to the family of retroviruses.

The Relation Between an Autism Gene and Infertility

The biological foundations of a reproductive disease caused by a DNA mutation have been discovered by a University of California, Riverside study. Fragile X Syndrome, a major genetic contributor to cerebral impairment and autism, is also caused by this gene mutation.

The “Hangry” Stage of Bacteria Cells

The word “hangry” describes individuals who become angry due to hunger. According to a recent study by Adam Rosenthal, PhD, an assistant professor in the department of microbiology and immunology, some bacteria cells experience hangry and release toxic substances into the body when they are denied certain nutrients.
