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).

$1.65 Million Grant Awarded for Advancing Therapeutic RNA Design

A team led by Dr. Samie Jaffrey, the Greenberg-Starr Professor of Pharmacology at Weill Cornell Medicine, has been awarded a three-year, $1.65 million grant for RNA research under a biotechnology-development program run by the U.S. National Science Foundation.

New Approach to Constructing Human Artificial Chromosomes Avoids Unintended Multimerization

Constructing human artificial chromosomes (HACs) in budding yeast overcomes the long-standing problem of uncontrolled multimerization – the rampant joining of similar molecules – and results in HACs that are large, stable, and structurally well-defined, researchers report.

New Biomarker Offers Early Detection of ALS and FTD

Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig's disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning -; the former affecting nerves in the brain and spinal cord leading to loss of movement, the latter eroding the brain regions controlling personality, behavior and language.
