Chapter 21 retrovirus Question - Multiple Choice Part A Do all viruses that contain RNA also have reverse transcriptase? Yes, all RNA viruses are retrovirus. No, some RNA viruses use the host machinery to make protein, but, no viral DNA is ever made. Yes, the only way to make replicate an RNA virus is to reverse transcribe the RNA into DNA. No, some RNA viruses also have DNA and do not need reverse transcriptase Yes, Reverse transcriptase is an enzyme in all viruses. Submit Request Answer

Health Epidemiology

Health is an essential factor for all human beings. For all humans, health is a critical factor. An individual's ability to meet life's challenges and retain his or her capacity for optimal functioning is reflected in his or her condition of health. This needs the physical, mental, and biological parts of one's constitution to maintain a degree of functioning that has a favorable influence and support for one another.
