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 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.

Trinity Scientists Discover New Mechanisms Involved in Establishing Cellular Identity

A team of scientists led by those in Trinity College Dublin has discovered new mechanisms involved in establishing cellular identity, a process that ensures the billions of different cells in our bodies do the correct job.

Viruses Interact with a Far More Diverse Set of Hosts than was Previously Thought

Viruses are the most abundant and diverse biological entities on Earth, living in every type of habitat. In the ocean alone viruses are ten times more abundant than microbes.

Evolutionary Encounter of Two Protein Components Could Occur Entirely by Chance

Proteins are the key players for virtually all molecular processes within the cell. To fulfil their diverse functions, they have to interact with other proteins.

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.

DELLA Proteins: The Road to the Next Green Revolution

Despite being largely unchanged for over 450 million years, a family of “promiscuous” proteins that are present in all land plants is responsible for a wide range of plant activities.

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.

Experts Develop a New Mesoscopic Simulation Model of DNA Movement

The mesoscopic scale in physics and chemistry relates to the length scale on which the properties of a material or phenomenon can be researched without delving into the behaviour of individual atoms.

Revealing how cohesin attaches to the DNA and forms loops

Ana Losada, a scientist at the Spanish National Cancer Research Centre (CNIO) and then at the Cold Spring Harbor Laboratory, identified cohesin, a protein essential to the process of cell division, in Xenopus frogs at the end of the 1990s.

Male Beetles Neglect Maintenance of Gametes When Competing for Mating Opportunities

Male beetles face a trade-off between competing with other males for mating opportunities and repairing damage to their sperm DNA, according to a study publishing April 4th in the open access journal PLOS Biology by Mareike Koppik from Uppsala University, Sweden, and colleagues.

Novel Genes Could Serve as Predictive Biomarkers for PARP Inhibitor Response in Prostate Cancer

Prostate cancer tumors harboring BRCA1/2 mutations are exceptionally sensitive to PARP inhibitors, while genomic alterations in other DNA damage response (DDR) genes are less responsive.

Jumping Genes in Various Cancers may be Used to Direct Novel Immunotherapies to Tumors

New research from Washington University School of Medicine in St. Louis suggests that transposable elements in various cancers potentially may be used to harness novel immunotherapies against tumors that don't typically respond to immune-based treatments. Shown is a 3D rendering of cancer cells.
