Imagine if, for any given position in a list, there were only 4 values allowed:

A

T

G

C

What is the value of the next item in the list? Pure guessing and you have a 25% chance of being right. But what if a review of past lists allows you to develop weighted averages, to the point where you could be, say, 70% correct? What if there was a way to do multiple scans, such that the chance of correctness gets to be some value of 99.x% ?

Imagine the 4 values stand for:

Adenine

Thymine

Guanine

Cytosine

It seems to me there is here suggested a new way of parsing a genome. I have friends who've worked on automated cancer detection based on recognizing certain patters in photos of cells. Possibly similar techniques could take electron microscope scans and figure out a sequence of DNA?
