Cambridge University scientists say they have seen four-stranded DNA at work in human cells for the first time. They suggest that control of the structures could provide novel ways to fight the disease.
“The existence of these structures may be loaded when the cell has a certain genotype or a certain dysfunctional state,” said Prof Shankar Balasubramanian from Cambridge’s department of chemistry. “We need to prove that; but if that is the case, targeting them with synthetic molecules could be an interesting way of selectively targeting those cells that have this dysfunction,” he told BBC News.
