How cells keep genomic hitchhikers under control
Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost their ability to copy themselves into new locations but can still cause problems if they become active again at…
AI Summary
Cells have developed mechanisms to control genomic elements that were once mobile but have lost their ability to replicate. These elements, remnants of ancient genetic material, can still cause issues if they become active at the wrong time. Cells have a system in place to keep these elements under control, as revealed by two studies from FMI scientists published in Molecular Cell.
