Noncoding (that is, “junk”) DNA helps cells avoid starvation

Some researchers wondered whether all that junk DNA supposedly left over from Darwinian evolution actually did something after all so they tested the idea: Patches of seemingly meaningless DNA dotted throughout the genome might actually have a function: helping cells to survive starvation. Two studies published in Nature on 16 January suggest that these stretches of non-coding DNA called introns help to control the rate at which cells grow, conserving energy when food becomes scarce. Michael Marshall, “Cryptic DNA sequences may help cells survive starvation” at Nature Not just “junk DNA” any moreat The Scientist either, it would seem: Two studies contest the idea that the noncoding sequences are just “junk DNA,” demonstrating that they play important roles in the regulation of Read More ›
