I'm looking for a lethal mutant allele (D50) of the largest subunit of RNA
polymerase II. This mutation is caused by the insert of a 1.3 kb P-element
insert 5' to the start site of transcription of RpII215. The original
stock was y mei-9(a) RpII215(D50) mei-41(D5). If anyone can help me track
down this stock, I would greatly appreciate the information.
