Large-scale sequencing efforts have revealed frequent BAF complex mutations in many human diseases, particularly in cancer and neurological disorders. birthday wishes to our clientThe role of nucleosomes is a very important topic of research. 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. birthday wishes to my son from mother
