...arly. Del Bene and Wittbrodt showed that when SIX3 locks onto it, GEMININ is unable to stop division, and the tissue grows to its proper size. When the cells have reached their normal size, GEMININ needs to unlock itself from SIX3 to become active again, so that tissues don't become too large. Building the...Nation on the verge of 'new era in modern river management'
