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.

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.
