Researchers led by Imperial College identify the formation of quadruple helix DNA in healthy living human cells for the first time, tracking how it works, as well as its possible role in cancer. The team states they engineered a fluorescent marker possessing the ability to attach to quadruplex DNA in living human cells, allowing them to define for the first time how the structure forms and what role it plays in cells.

Formation of quadruple helix DNA tracked in live healthy human cells.

Described as a inbuilt program for making all the proteins vital for the body to survive and function, DNA or deoxyribonucleic acid is an elaborate molecule first discovered in 1869 … Continue Reading Formation of quadruple helix DNA tracked in live healthy human cells.

Researchers identify new enzyme critical to maintaining human telomere length.

Telomeres are repetitive nucleotide sequences located at the termini of chromosomes.  Telomere shortening in humans can induce cellular old-age, which blocks cell division. This mechanism prevents genomic instability and development … Continue Reading Researchers identify new enzyme critical to maintaining human telomere length.
