Introduction:
The recombinant DNA technology involves isolation of genetic materials (DNA) from donor organisms (human, plant, or microorganism) and inserts them into recipient organisms after genetic manipulation. The main tools involved in the techniques are

- When E. coli cells are mixed with recombinant vector DNA and subject to a stress such as heat shock, a small fraction of the cells will take up the plasmid DNA, a process known as : A. Ligation. B. Transformation. C. Transfection. D. Digestion.arrow_forwardFor each situation, write the letter of the technique that would be most helpful; A. DNA editing A doctor wants to know if a patient has an inherited using CRISPR B. DNA replication using PCR C. DNA analysis through genetic testing D. DNA insertion 16. disorder. I A scientist needs many copies of a gene to conduct an 17. experiment. A genetic engineer wants to replace a defective copy of a gene with a functional copy in a chromosome. 18. into bacteria as a plasmid A medical researcher needs many copies of a protein 19. (insulin) to be produced to use in a medical treatment. A researcher crossed two purebred shrubs of the same species. One produces a fruit with a thin skin, and one produces a fruit with a thick skin. All of the plants resulting from the cross produce fruits with thick skins. Enter one letter in each blanks (19 & 20) to correctly complete the sentences. ninate Education TM, Inc.arrow_forwardA graduate student isolates two new retroviruses: Virus A and Virus B. To determine whether these viruses could cause cancer, the student infected human cells with each of the viruses and then transfered the infected cells to nude mice to see if the viruses would cause formation of tumors. The student was able to determine by PCR that both viruses are integrated into the genome of the host cells before transplanting cell in mice. The data for this assay are shown in the figure below. Explain how the mechanism of transduction may be different for these two viruses to yield the observed data (limit 4-5 sentences).

- What is vector? Discuss 2 vectors that are commonly used in DNA recombinant technology.arrow_forwardDiscuss the four important features of DNA vectors.arrow_forwardCHOICES: a. Plasmid b. Sticky end c. DNA ligase d. Transformation e. Restriction enzyme f. Genetic marker g. Transduction QUESTIONS: Cuts the DNA into fragments Circular DNA molecule of bacteria Used to insert DNA of interest to vector Area of DNA where bases are ready to be paired Recombinant DNA technology with the help of a vector genearrow_forward
- Discuss the process and give example on the following. a. Aptamer Biosensors b. CRISPR c. Stem Cell Therapyarrow_forwardAmong the following statements regarding the use of viral vectors, which is (are) true: (can be more then one answer) A.Viral vector transfection has the defect of rapidly killing cells, given the high toxic potential of viruses. B.Generally, the effectiveness of a viral infection transfection is much higher than an electroporation or cationic liposome transfection. C.Even before infecting a cell, a virus can begin to express the indicators, accelerating the process of expression of the indicator in the culture medium. D.Adeno-associated viruses are little used in biophotonics, as they require simultaneous adenovirus infection.arrow_forwardwhich of the following do researchers not need to use during vector cloning? a. a plasmid containing selectable marker genes such as beta galactosidase or ampicillin resistance genes. b. restriction enzymes. c. DNA polymerase d. a growth medium with carefully selected ingredients that take advantage of selectable markers. e. none of the above.arrow_forward
- If you are a genetic engineer and you cloned your gene of interest in a plasmid and you want to know if the protein encoded by the cloned gene is expressed or not, which of the following methods is the right one to use? Select one: a. Northern blot b. Both Northern and Western blots c. Agarose gel with polyacrylamide d. Western blot e. Protein gel and northern blotarrow_forwardA has been assembled by researchers and transplanted into a donor bacterial strain to study never before seen gene functions. Select one: a. Transgenic genome b. Recombinant DNA sequence c. Knockdown gene d. Synthetic genome o e. Recombinant plasmid Clear my choice is changing our Sequencing the human genome, the development of microarray technology, and understanding of complex diseases like cancer. They help us to observe the gene expression patterns in genetic disease by comparing the healthy tissue of individuals against the disease state of others. Select one: C a. Proteomics o b. Metagenomics MO C. Functional genomics d. Personal genomics O e. Developmental genomics Clear my choicearrow_forward5) Below is an image that shows both reproductive and therapeutic cloning. Use this image to answer compare and contrast therapeutic and reproductive cloning. Are they used for similar means…etc. Once you have done that answer the question below. a) There are two types of therapeutic cloning. What are they and how are they different?arrow_forward
