There is a special room reserved in hell for lazy scientists. Especially lazy scientists who get jobs at Harvard, publish papers in Cell (super-top tier science journal) using DNA constructs that aren’t what they claim they are, and then send those constructs to other labs, only to have the other labs find out that a) there are point mutations in three out of the four constructs you received; and b) one of the deletion mutants is deleted in a spot that is different from what you were told. This makes a difference.
I would have been better off making these constructs from scratch myself. Trust no one, and all that.
