5-bromouracil resembles thymine enough to become incorporated into DNA during replication. Once incorporated, it rearranges to resemble cytosine. If 5-bromouracil was present during the replication of the sense strand shown below, which of the following might be the sense strand formed in the following replication?
5' -GGCGTACG -3'
A. 5'- GGCGCACG -3'
B. 5'- GGCGATCG -3'
C. 3'- CCGCAGGC -5'
D. 5'- GGCGTGCG -3'
answer is D.
I've been trying to figure this out for way too long. I would write my logical progression, but it's gone all over the place and i'm extremely frustrated :<
If it helps, the book gives the following:
---------------------------------------------------------Original is 5'- GGCGTACG -3'
new anti sense strand in presence of bromouracil: 3'- CCGCABGC -5'
---------------------------------------------new sense strand: 5'- GGCTGGCG -3'
thanks.
