Which of the following are examples of post- translational modification (PTM)? (select two answers) Genomic DNA is methylated by a DNA methyltransferase, altering the binding of transcription factors. Glycogen phosphorylase becomes active when phosphorylated by glycogen phosphorylase kinase. Glucose is phosphorylated by hexokinase as the first step in glycolysis. Ras is active when bound to GTP, and inactive when bound to GDP. Caspase 3 is activated when cleaved by capsase 9.
