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. OC 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.

What are the potential benefits and disadvantages of using bacteriophages in place of antibiotics? Write at leat two paragraphs

You have found a gene of interest in an animal in the rain forest which produces a unique protein that will blocks reproduction of the pathogen that now plagues the world. You wish to mass produce this protein using bacteria. Answer the following questions regarding the scenario above.  Describe how you would remove the gene of interest out of the isolated animal cell.  What type of vector, (delivery system), would be best used to get the gene into the bacteria? How would you insert the gene of interest into the vector? How would get the vector into the bacteria? Why would the bacteria express this gene even if it normally does not have use for this protein?

Transformation is a form of horizontal gene transfer that involves random mutation. physical contact between cells. viral infection. acquisition of DNA from the environment.
