Does anyone have any info (reference?) on this i.e. is it True? I cant find any reference to this activity in the PCR textbooks. I've successfully cloned lots of PCR products in the past but as I put sites on the ends I've never looked for extra A's. Apologies if you've read this before but my mail failed last time Thanks Chris Jones Biochem Dept Nottingham Univ. Brought to you by Super Global Mega Corp .com
