Transcription factors that are bound specifically to DNA often interact with each other over thousands of base pairs [1] [2]. Large DNA loops resulting from such interactions have been observed in Escherichia coli with the transcription factors deoR

H2A-H2B exchange with the intranuclear histone pool upon chromatin transcription in vivo is generally viewed as being triggered by the DNA positive supercoiling wave pushed by the elongating polymerase. This notion was tested here by investigating a

Tn4430 is a distinctive transposon of the Tn3 family that encodes a tyrosine recombinase (TnpI) to resolve replicative transposition intermediates. The internal resolution site of Tn4430 (IRS, 116 bp) contains two inverted repeats (IR1 and IR2) at th

The conformational changes induced by the introduction of a central and unique single-stranded break in a 139 base-pair DNA duplex have been analysed by means of polyacrylamide gel electrophoresis, HPLC and dark-field electron microscopy. Compared to

The left-handed form of poly (dG-m5dC).poly(dG-m5dC) induced by heating the copolymer in the presence of magnesium and stabilized with polyarginine can be used to raise antibodies in rabbits. These antibodies are able to recognize the Z conformation
