Question 12
The de Bruijn graph of some linear (i.e., non-circular) genome Dna comprises of 2 nodes (N1 and N2) and 6 edges – three of these edges are directed from N1 to N2 and the remaining three edges are directed from N2 to N1. To reconstruct Dna, you are allowed to start only from the node N1. Answer the given subquestions with respect to the same.
Suppose you don’t know the 2-mers representing N1 and N2. Then which of the following is/are possible choices for Dna?
