The role of acetylation in rDNA transcription.

abstract：:We have developed an HIV nef-Escherichia coli lacZ fusion system in vitro that allows the detection of low frequency mutations, including frameshifts, deletions and insertions. A portion of the nef gene that encompasses a hypervariable region was fused in-frame with a downstream lacZalpha peptide coding region. The re...
