Dear netters

        I'm afraid this is a primitive question. Does anybody know why we
have to add single-stranded calf-thymus DNA to the S1 nuclease digestion
buffer in S1 nuclease mapping of mRNA. Without the DNA, what will happen ?
I will greatly appreciate it if somebody teach me. Sorry again for this
stupid question ?

Sincerely yours,
