#Unit 3. Fundamental Processes

Direct repeats can be displaced and misaligned with the template; palindromic sequences can form hairpins. These structures may change the number of repeats. The general importance of FEN1 is that it prevents flaps of DNA from generating structures that may cause deletions or duplications in the genome.

The shifts of hydrogen atoms between the number 3 and number 4 positions of the pyrimidines and between the number 1 and number 6 positions of the purines change their base-pairing potential due to Tautomeris
