Microbiology: P4 Microbial Genetics-Genetic Eng and Gene Therapy
| Question | Answer |
|---|---|
| What is the artificial introduction of changes to the genes in a cell? | Genetic Engineering |
| Gene Therapy or Genetic Eng: Deliberate modification of an organism's genetic information by directly changing its genome | Genetic Engineering |
| Gene Therapy or Genetic Eng: The insertion of a normal gene into cells to correct a specific genetic or acquired disorder that is being caused by a defective gene | Gene Therapy |
| What is a novel approach to treat, cure, prevent disease by changing the expression of a person's genes? | Gene Therapy |
| T or F: Gene Therapy is in its infancy and current gene therapy is primarily experimental, with human trials only in the research stages? | True |
| What does Genetic Engineering apply recombinant DNA technology? | (1)It is a direct manipulation of an organism's genes by the artificial introduction of a gene into a cell (2)Uses molecular cloning and transformation to alter the structure and function of genes |
| What is a retrovirus? | A virus that stores genetic information in the form of RNA, uses Reverse Transcriptase to incorporate genes into host cell genome |
| What is the purpose of Genetic Eng? | It can allow or genes of interest to be "fixed" to change the protein---restoring function of the cell |
| How does Gene Therapy cure, treat, or ultimately prevent disease? | Inserting normal gene to correct a genetic/acquired disorder that is being caused by defective gene---Changes expression of a person's genes |
| In what year was the first gene therapy attempted? | 1989--Maurice Kuntz |
| What was the impact of the Jesse Gelsinger case? | In 1999 Gene therapy took a major halt, because the study resulted in the unnecessary death of Jesse |
