For example, if an enhancer-binding protein is detected by ChIP at a distal promoter that lacks binding sites for this factor, this might result from the enhancer having looped to the promoter (e.g. [24]).An obvious caveat to this …
WebLampbrush Chromosome. The lampbrush chromosomes have the lateral loops that extrude from the chromomeres at certain positions. Chromomeres are the beads that appear at the meiosis stage in which the chromosomes resemble a series of beads on a string. The loop is an extruded segment of DNA that is being actively transcribed.
