Bacterial protein builds DNA sans template
A team of scientists has discovered a protein called Drt3b that can construct DNA without the need for a pre-existing template. This is a significant discovery that opens new horizons in the technology of DNA molecule fabrication. The protein uses its unique shape as a template to correctly position the building blocks where they belong. This finding is unexpected, as it was previously believed that DNA could only be copied from an existing strand. It is considered a potentially groundbreaking step toward developing new genetic techniques, although researchers are still at the early stages of understanding its capabilities and how to control them.
