Transcription is the process cells use to copy information from DNA into messenger RNA copies. Part of the chromosome's tightly wound-up long strand of DNA is "loosened" to allow for RNA polymerase room to copy part of the DNA. Think of this as opening a page out of a giant book with thousands of pages to make a copy of just that one page. One side of the DNA strand is the template strand (or anti-sense strand) and is used by an enzyme called RNA Polymerase to create the messenger RNA. RNA Polymerase is directed by a bunch of proteins called transcription factors to the spot it needs to start copying. RNA Polymerase reads the template strand from the 3' end to the 5' end and creates a messenger RNA strand that is complementary to the template strand. In the diagram above, you can see that…TAN TTGC IGGAG Nanog regulatory sequence Given this interaction map which DNA sequence would the transcription factor most likely bind to?
