When do cells need to carry out transcription? Select all four (4) that apply. 1. When the cell needs enzymes to do a metabolic process. 2. When the cell needs to produce a special secretion or product, for example when you eat a meal and cells in the stomach need to secrete trypsin enzyme for digestion. 3. When the cell needs to make new proteins to perform any function in the cell. 4. When the cell condenses its chromosomes in preparation for cell division. 5. When current enzymes and proteins get broken down and need to be replaced. 6. When the cell needs to make a copy of its genome to pass it down to the next generation.
