A new technique for rapidly determining the nuclesome structure for regions of chromatin is called Mnase-Seq. Briefly, in MNase-Seq experiments, the chromatin is digested with Micrococcal Nuclease (MNase) and then the resulting digest is subjecting to high throughput sequencing to identify sequences digested by enzyme. See this short article for complete explanation. In the experiment below, researchers conducted an Mnase Seq experiment on a region of a chromosome in the absence (OHT-) and presence (OHT+) of a Protein X. This protein has a dramatic effect on the expression of the Igll1 gene, but no effect on Top3b nor Vpreb1 genes. Based on this information, explain what Protein X is doing to influence the Igll1 gene (limit 4-5 sentences).

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
