WebA model for binding Glu and Lys to dsDNA was explored by a docking simulation. The model shows that Glu, in an untwisted shape, binds to dsDNA in its major groove and disrupts three H-bonds between the strands, thereby destabilizing the double helix. WebMost activators function by binding sequence-specifically to a regulatory DNA site located near a promoter and making protein–protein interactions with the general transcription machinery ( RNA polymerase and general transcription factors ), thereby facilitating the binding of the general transcription machinery to the promoter. birth cert application nswWeb12th May, 2024 Ethidium Bromide Binds to DNA. ...
