Presenter notes contain extra information which might be useful if you intend to use these slides for teaching. Press `P` again to switch presenter notes off Press `C` to create a new window where the same presentation will be displayed. This window is linked to the main window. Changing slides on one will cause the slide to change on the other. Useful when presenting. --- ## DNA Methylation data analysis ## -- ##Bisulfite sequencing QC and processing in Galaxy --- #Biological background ---  --- .image-75[] --- #Methylation: What is it good for? - Suppression of repeats - Gene expression - Imprinting - X-chromosome inactivation - Chromosome stability - Development - Changes in cancer - Changes with age --- #Heritable methylation .image-50[] .image-25[] <small>Weaver et al.
