DNA molecules can display what almost seems like telepathy, research now reveals. Double helixes of DNA can recognize matching molecules from a distance and then gather together, all seemingly without help from any other molecules, scientists find. Previously, under the classic understanding of DNA, scientists had no reason to suspect that double helixes of the molecule could sort themselves by type, let alone seek each other out. Scientists investigated double-stranded DNA tagged with fluorescent compounds. These molecules were placed in salt water that contained no proteins or other material that could interfere with the experiment or help the DNA molecules communicate. Curiously, DNA with identical sequences of bases were roughly twice as likely to gather together as DNA molecules with different sequences. Although it looks as if spooky action or telepathic recognition is going on, DNA operates under the laws of physics, not the supernatural. The bases that make up a strand of DNA each cause the corkscrew to bend one way or the other. Double-stranded DNA with identical sequences each result in corkscrews whose ridges and grooves match up," said researcher Sergey Leikin, a physical biochemist. Identical DNA double helixes have matching curves, meaning they repel each other the least, Leikin explained. The scientists conjecture such "telepathy" might help DNA molecules line up properly before they get shuffled around. This could help avoid errors in how DNA combines, errors that underpin cancer, aging and other health problems.
