NewsBacterial ‘flipping’ allows genes to assume different forms
A new study has shown that inversions, which cause a physical flip of a segment of DNA and change an organism’s genetic identity, can occur within a single gene, challenging a central dogma of biology — that one gene can code for only one protein.
