Three different restriction enzymes (A, B and C) were used to cut a linear fragment of DNA. Single and double digests were electrophoresed on an agrose gel and the following fragment sizes (in Kb) were observed in the gel:

A: 6+8 B:11, 13 C: 3,9,12
A + B: 5,6,13 A + C: 3,9 B +C: 3,4,8,9

Draw a restriction map of the molecule that completely explains these results. For full credit, you must show your work by drawing maps of the double digest.

you don't have any picture of the problem?

anonymous · Answer

No i didn't receive a picture ..

anonymous · Answer

are you 100% sure those are the correct answer?

anonymous · Answer

omg! sorry i meant A: 6, 18 not "+"

anonymous · Answer

Finally, I hope this is the correct answer. =)

anonymous · Answer

Thank you so much! Really appreciate it! 
I'm kind of new to restriction mapping, and i have no clue how to approach this question. Any chance you could explain the steps please?
