A new study has revealed that the existence of "personal" hand bacteria, as unique as a person's fingerprints and DNA, could become the latest weapon for forensics experts in their attempts to solve crimes and identify victims. According to a press release, the researchers at the University of Colorado at Boulder who conducted the study "swabbed bacterial DNA from individual keys on three personal computers and matched them up to bacteria on the fingertips of keyboard owners, comparing the...

PITTSBURGH -- Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers at the University of Pittsburgh, the University of Essex and the University of Vermont who tagged the proteins with quantum dots to watch the action unfold. The findings are available today in Molecular Cell. Everyone is constantly bombarded with environmental toxins that inflict small...

One of the biggest questions facing scientists today is how life began. How did non-living molecules come together in that primordial ooze to form the polymers of life? Scientists at the Georgia Institute of Technology have discovered that small molecules could have acted as "molecular midwives" in helping the building blocks of life's genetic material form long chains and may have assisted in selecting the base pairs of the DNA double helix. The research appears in the online early edition...

An inexpensive, fast, accurate DNA test that reveals a person's risk of developing certain diseases is expected to become a reality, thanks to technology developed at the University of Edinburgh. Scientists have developed a method of pinpointing variations in a person's genetic code at critical points along the DNA chain. The technique could be used to analyze DNA in a drop of saliva. Tiny differences or omissions in DNA code can determine whether or not a person is healthy, susceptible to...

WINSTON-SALEM, N.C., Jan. 29 /PRNewswire-USNewswire/ -- Meet Kenny Twist and the DNA girl. They are the stars of a new animated film, "Cell Side Story," developed by students at Atkins Academic and Technology High School in cooperation with Wake Forest University and other community partners. "Cell Side Story" is a love story featuring male and female animated characters that dramatize what happens within cells. Kenny Twist represents kinesin, a motor protein found within cells. The DNA...

U of Minnesota researcher leads study Researchers at the University of Minnesota have discovered a molecular security system in human cells that deactivates and degrades foreign DNA. This discovery could open the door to major improvements in genetic engineering and gene therapy technologies. Led by Reuben Harris, associate professor of biochemistry, molecular biology and biophysics in the College of Biological Sciences, the report's findings was published online by Nature Structural and...

Optical approach measures molecular kinetics in living cells Our cells' molecules form an intricate network of interactions. Today's techniques, however, can only be used to measure individual molecular reactions outside the cells. Since molecular concentrations are much higher in cells than in the laboratory, scientists suspect that the kinetics of molecular reactions in living cells differ substantially from external probes. "žWe expected the cellular reaction speed to be...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...
