Chapter 12, Problem 1SQ

Suppose you wish to create a large batch of the protein lactase using recombinant DNA. Place the following steps in the order you would have to perform them.

  1. a. Find the clone with the gene for lactase.
  2. b. Insert the plasmids into bacteria and grow the bacteria into clones.
  3. c. Isolate the gene for lactase.
  4. d. Create recombinant plasmids, including one that carries the gene for lactase.

Summary Introduction

To determine: The sequence of steps that will performed by the individual if he wants to create a large batch of protein lactase using recombinant DNA.

Introduction: Recombinant DNA technology involves excising the DNA of interest from one genome and inserting into a foreign genome by identification, isolation, manipulation and re-expression of genes.

Answer to Problem 1SQ

Correct answer: The order of the steps for producing large batch of the protein lactase using recombinant DNA are c.,d.,b. and a.;

c. isolate the gene for lactase,

d. create recombinant plasmid, including one that carries the gene for lactase.

b. insert the plasmids into bacteria and grow the bacteria into clones,

a. find the clone with the gene of lactose.

Explanation of Solution

Recombinant DNA technology is a process that includes transfer of a desired DNA sequence or genes from one organism to a self replicating genetic element such as bacterial plasmid followed by propagation in host cell. The steps involves in the formation of recombinant are as follows;

  • The gene of interest is identified and isolated and inserted into plasmid (vector). The joining of DNA from two different sources results in the formation of recombinant DNA plasmid.
  • The recombinant plasmid is inserted into the bacteria for multiplication. Under the right condition, the bacteria take up the recombinant plasmid.
  • Each bacterium carrying the recombinant plasmid is allowed o reproduce through the cell division to form the clones of cells.
  • The identified transgenic bacteria with the gene of interest can be grown in tanks to produce a large amount of desired protein.

In relation to the use of restriction enzymes in recombinant DNA technology, answer the following:  You have accidentally torn the labels off two tubes (tube A and tube B), each containing a different plasmid, now you do not know which plasmid is in which tube. Fortunately, you have restriction maps for both plasmids, shown in Figure below. You have the opportunity to test just one sample from one of your tubes. By utilizing agarose gel electrophoresis technique, which restriction enzyme OR combination of restriction enzymes would you use in this experiment to determine which plasmid is found in which tube?. (Hint: if you use Hind III restriction enzyme you are going to get ONE single fragment with a molecular size of → 0.5+0.3+0.2+0.4+1+1 = 3.4 kb).
In gene cloning, a vector is required to transform the gene of interest into host cell. State the THREE (3) important regions of the plasmid. Elaborate your answer.
A company that manufactures cleansing products has synthesized two new organic compounds , chemicals A and B, which improve the cleaning power of dishwashing detergents. To determine the mutagenic capacity of the chemicals , the company tested the effect of the chemicals on Salmonella cells requiring histidine to grow ( His- cells ). The table below shows the results of the test . A. Name the test used by the company . B. What does the test detect or estimates ? C. Which chemical (s) would you identify as containing a mutagen ? Why ? D. What is the purpose of test 1 ? Why are colonies detected in test 1? E. Which chemical ( s) would you identify as possible antimutagen ? Why ?
