The answer is true. As you move across the periodic table, the elements have a higher atomic charge due to an increase in the number of protons and neutrons. Since the neutrons have no charge, the protons (that have a positive charge) attract the electrons clouds that are negative in charge (unlike poles attract). The more the protons in an atom, the more the attraction on the electron orbits so they get closer to the nucleus of the atoms. This is the reason the atomic diameter reduces across the periodic table.
As activators that increase transcription initiation or decrease action of transcription initiation of related gene, transcription factors that bind to enhancers have an impact on genes thousands of base pairs distant.
Because the DNA between the enhancer and the promoter loops out, transcription factors bound to the enhancer can communicate with the basic transcription machinery directly. A few proteins that act as transcription regulators bind to enhancers, that are regulatory components located outside the gene they are meant to activate. DNA sequences known as insulators prevent enhancers from working. Insulators may work by creating chromatin loops that connect interconnected areas of genes and regulatory components.
