Summary Introduction
Introduction: Retrovirus is a widespread infectious agent that has been identified in many eukaryotes including humans. Retroviruses are of great importance as they are mostly linked with diseases such as AIDS and cancers. Retroviruses are icosahedral viruses that have an envelope. They have single-stranded RNA as genetic material.

- Which of the following is a concern of in-vivo gene therapy? A. Lytic vector expression B. Integration into target region C. Immune response to viral vector D. Production of chimeraarrow_forwardBacteria exposed to viruses incorporate sections of the virus’s DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as “coordinates” for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell. Explain why: 1. The invading phage DNA is recognized by the Cas proteins but not inserted into the CRISPR array region of the bacterial genome: The bacteria will be unable to elicit an immune response and will succumb to the phase infection 2. The cas genes on the bacterial genome contains a missense mutation that increases its cleavage/cut activityThe bacteria will elicit an immune response that will successfully fight the phage infectionarrow_forwardWhat carries a gene from one organism into a bacteria cell? a. a plasmid b. an electrophoresis gel c. a restriction enzyme d. polymerase chain reactionarrow_forward
