Discovery of DNA in cells is in 2018 the "Discovery of the Year" for the journal Science

New technologies capable of showing how DNA sends a signal to each cell to develop over time were described this Thursday in the "Discovery of the Year" of 2018 by the American magazine Science.

According to experts, these methods will transform science in the coming decades, providing an increasingly accurate view of the aging, healing and disease processes.

"Just as a musical score indicates when string instruments, wind instruments and percussion instruments need to play to create a symphony, a combination of technologies shows when the genes in each cell are activated and signal the cells to play their part. specialized paper, "the magazine said.

"The result is an ability to track the development of organisms and organs with an impressive level of accuracy, cell by cell, over time," he said.

Modern methods are backed by Nobel laureate John Sulston and his colleagues "who mapped the development of a worm, Caenorhabditis elegans, observing microscopically how the larvae grow cell by cell," Jeremy said. Berg, editor of the Science group magazines.

"With current technologies, particularly parallel large-scale DNA sequencing and advanced fluorescence microscopy, Caenorhabditis elegans cells were mapped again using identification, assay and assembly methods based on the behavioral model of the genes within each cell," he said .

Articles were published this year on how a flatworm, a fish, a frog and other organisms are beginning to produce organs and limbs.

Scientists are working hard around the world to use these techniques in human cells: the way they age and regenerate, as well as changes that cause cancer, diabetes or other physical malformations.
