In addition to the artistic allure of the DNA structure
itself, DNA-fingerprinting patterns have inspired interesting new art.
Summary: TEHRAN (FNA)- Iranian researchers produced new nanobiosensors by designing and manufacturing appropriate bed for the stabilization of one of four-chain DNA structures
entitled G-quadruplex in order to identify compounds attaching to this structure through various mechanisms.
For example, while DNA structures
hold promise for biological applications, their ability to resist enzymes, to penetrate into cells and their safety in organisms all need to be examined and optimized.
In layman's terms, each of us comes with our DNA structure
that's unique to us.
The oxidation of biomolecules by the radicals damages the DNA structure
and biological activity.
The DNA structure
is a whole lot more pliable than we originally thought, and that's fascinating," comments Floyd Romesberg, a molecular biologist at the Scripps Research Institute in La Jolla, Calif.
The international cast of academics describes angiosperm resurrection plants, lichens, gene expression, dry seeds and pollen, DNA structure
, and desiccation damage in plant reproductive organs.
Gagna's discovery will help scientists understand how transitions in DNA structure
regulate gene expression (B-DNA to Z-DNA), and how DNA-protein, and DNA-drug interactions regulate genes.
We used a suite of complementary biomarkers to signal contaminant-induced changes in the DNA structure
and cellular physiology of the livers and gills of English sole (Parophrys vetulus).
It is to be noted that although the terms 'genetic sequence', 'nucleotide sequence', 'genome sequence' and any other term involving or referring to DNA are retained in this discussion to match the usage in contemporary scientific literature, they should be taken to imply a chromosomal region or a chromosomal sector, but not specifically the DNA structure
that stores a program bit.
Dr Swan said: 'The free radicals can break down the DNA structure
of our existing cells, which then leads to the risk of the body making replacement rogue cancer cells.
Dr Mark Birch-Machin, a molecular dermatologist at Newcastle University, has devised a sunscreen that prevents damage to the skin's DNA structure
by ultraviolet (UV) light.
We attempted to form a stable triplex DNA structure
within an eight base pair bulged/mismatched region of a 32 base pair length DNA duplex using coralyne as a stabilizing intercalating molecule for the triplex.
A UV-light chamber ensures that any remaining bacteria or viruses are completely neutralized by altering their DNA structure
before the air continues on its normal route.
18) What few people realize, he points out, is that the double-helical DNA structure
may not be correct and is certainly not the only way in which DNA exists in chromosomes.
