Don't worry, it should be. Your epidermis is the top part of your skin, and your skin is your body's largest and fastest-growing organ. Skin is your body's coat. It protects you. It helps you stay warm when it's cold, and cool when it's hot. Your skin keeps all your insides in, from your heart and lungs to your blood and muscles.
In the other population of cells, the injected phage chromosome turns OFF all the phage genes except one. The single phage chromosome called the prophage now becomes a part of the host chromosome. The bacterium carrying the dormant phage chromosome is called the lysogen.
Testing for BCR-ABL detects the Ph chromosome (the derivative chromosome 22) and BCR-ABL fusion gene or its transcripts, the RNA copies made by the cell from the abnormal stretches of DNA. The presence of the BCR-ABL abnormality confirms the clinical diagnosis in CML and a type of ALL.
