In human cells, scientists find DNA that looks like a twisted knot instead of a double helix
(Worthy News) – For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.
The tangled shape, known as an i-motif, had been seen before in the lab, but few researchers expected it to occur in human cells.
The new work shows not only that i-motifs do indeed exist in human cells, but that they may be quite common. [ Source: LA Times(Read More…) ]
