It is known that nucleosomes interfere with the binding of transcription factors to DNA, therefore they can control transcription and replication. With the help of an in vitro experiment using yeast, it was discovered that RSC is required for nucleosome remodeling. There is evidence that RSC does not remodel the nucleosomes on its own; it uses information from enzymes to help position nucleosomes. birdy land dour
