Since the displaced who is intended to modify the professor in this sentence, reactivation of antecedent the professor at who refers to the process of gap filling.
12.
The Pol ? ( Pol4 in yeast ) fill gaps during NHEJ . Yeast lacking Pol4 are unable to join 3'overhangs that require gap filling, but remain proficient for gap filling at 5'overhangs.
13.
SSA is employed as a repair pathway when a double-strand break arises between direct repeat sequences in DNA . SSA involves single-strand resection, annealing of the repeats, flap removal, gap filling and ligation.
14.
The Pol ? ( Pol4 in yeast ) fill gaps during NHEJ . Yeast lacking Pol4 are unable to join 3'overhangs that require gap filling, but remain proficient for gap filling at 5'overhangs.
15.
The small, excised, damage-containing DNA ( sedDNA ) oligonucleotides are initially released from the duplex in complex with TFIIH but then dissociate in an ATP-dependent manner and become bound to RPA . Inhibition of gap filling DNA synthesis and ligation results in an accumulation of RPA-bound sedDNAs in the cell.
