Scientists detect Bubbling sound whizzing around in DNA

A new research in the UK has detected sound-like bubbles in DNA that is essential to life and which will change the fundamental understanding of biochemical reactions inside a cell.

The research, which was carried out by academics from the University of Glasgow and published in ‘Nature Communications’, describes how double-stranded DNA splits using delocalized sound waves that are the hallmark of quantum effects.

DNA contains the code to life and holds a blueprint for each and every living thing on earth.

Dedicated enzymes responsible for making new proteins read the code by splitting the double strand in order to access the information.

One of the big outstanding questions of biology has been how these enzymes find the initial hole or “bubble” in the double strand to start reading the code.

“It is believed that DNA has regions where a specific sequence of bases modifies the stiffness of the double helix favouring the formation of bubbles. This causes a break of the weak bonds between the strands showing the transcription and replication enzymes where to start their task,” Mario Gonzalez Jimenez, a researcher said.

Another researcher Gopakumar Ramakrishnan said: “It had been

proposed by theoreticians that such DNA bubbles might behave like sound waves, bouncing around in DNA like echoes in a cathedral. However, the current paradigm in biology is that such sound-like dynamics are irrelevant to biological function, as interaction of a biomolecule with the surrounding water will almost certainly destroy any of these effects.”

Researchers in the Ultrafast Chemical Physics group carried out experiments with a laser that produces femtosecond laser pulses about a trillion times shorter than a camera flash.
