You provide all the following reasons EXCEPT you make one mistake. Which statement below is FALSE with regard to why viruses are not considered cells?arrow_forwardWhich of the following is inconsistent with the central dogma? a) An RNA molecule that can self-replicate b) A chromosome that is duplicated before cell division c) A protein that converts its own amino acid sequence into a DNA sequence d) A retrovirus (e.g. HIV) that transcribes its RNA genome into DNA inside its host e) A gene being translated into a proteinarrow_forward
- As a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.arrow_forwardAll the followings are biological acellular entities except: a) Bacteriophages b) Bacteria c) Viroid d) Virions e) Prionsarrow_forwardLacking ribosomes, how can viruses be placed on the universaltree of life?arrow_forward
- What is the origin (or origins) of viruses? Is there evidence that viruses have multiple origins? Show us the evidence.arrow_forwardUse the information to answer the following question. Two students were debating whether viruses are living or nonliving. Student A: Viruses are living because they contain DNA or RNA and reproduce. Student B: Viruses are nonliving because they do not grow and do not use energy. Which student's claim is correct and why? O A. Student B, because viruses do not use or make energy. Even though they contain DNA and RNA, many other non-living things also contain DNA and RNA. O B. Student B, because viruses do not grow and do not use energy. Although they have DNA and RNA, they are only able to reproduce with a host cell. O C. Student A, because viruses are able to reproduce and continue to spread their disease to other hosts. As the virus becomes more dangerous, it grows and becomes larger. O D. Student A, because all living things must have DNA or RNA. They must use energy in order to reproduce and make more viruses.arrow_forwardWhen Wimmer and coworkers announced that they had synthesized the poliovirus, they created considerable controversy. Some people feared that deadly and highly contagious viruses might be synthesized by bioterrorists. The researchers responded that they were merely applying current knowledge and techniques to demonstrate the principle that viruses are basically chemical entities that can be synthesized in the laboratory. Do you think scientists should synthesize viruses or other agents that can cause infectious disease? What are the implications of forbidding such research?arrow_forward
