2. Technique
Using techniques from Shotgun Chromatin/DNA Mapping (SCM/SDM)
we hope to map a variety of useful DNA structures/components. One
such application could be to map Telomeres.

How to unzip?
Using techniques established by others, it is possible to isolate a telomere
from other chromosomal DNA using cutting enzymes. We can attach the
telomere fragment to Koch’s unzipping scheme like any other DNA/chromatin
fragment.

Possible Unzipping Scenarios
A. Naked Telomere DNA
B. T-loop with proteins (TRF1 and TRF2 shown)
C. G-quadruplex structures on Naked Telomere DNA
D. (Unshown) Some combination of the above.
