Scientists from University of Sheffield identify process of removing DNA molecules from iconic double helical structure.
Q. Scientists from University of Sheffield announced the process of removal of DNA molecule from which structure?- Published on 08 Jun 16a. Double Helix
b. Triple Helix
c. Both of the above
d. Neither of the above
ANSWER: Double Helix
Scientists were trying to unlock this mystery for over 20 years. New research has unlocked the crucial part of mystery as to how human DNA can replicate and repair itself, essential for all life forms.
- Main findings of the research were that Branched DNA were identified in X-Files a TV serial. Researchers showed how Flap EndoNuclease enzymes (FENs) trim branched DNA molecules after cells have divided.
- They found the FEN threads the free end of the branch through a hole in the enzyme before sliding along to the trunk. It acts like a pair of molecular secateurs, trimming the branch and restoring the iconic double-helix.
- The team used the Diamond Light Source called the UK's synchrotron which works like a giant microscope for their discovery.
