Hello everyone,

I have a simple question to frequent/common is it for people to 
experience deletions/rearrangements when they are cloning their favourite 
gene?  I appreciate that the problem is likely to be strain-related and 
I have tried several different strains, finding my plasmid to be more 
stable in JM101 than any other.  But still, deletions occur.  We even 
jest about "vanishing genes".  Our lab often discusses possible toxicity of
some DNA sequences to E. coli and it has been suggested to us to try directly
transforming into yeast.  

I am interested to find out how often this sort of problem arises and how 
other labs approach and overcome it.  

Any thoughts would be appreciated.
