- Explain how bacteria are genetically engineered to produce human insulin.What is the purpose of cloning the human insulin gene in bacteria? Select one: To modify the human insulin gene sequence. To compare the DNA of the bacteria to that of the human insulin gene. To mutate the DNA of the bacteria. To produce identical copy of human insulin gene in large amount.Muscle cells differ from nerve cells mainly because they(A) express different genes.(B) contain different genes.(C) use different genetic codes.(D) have unique ribosomes.
- Give an example for any biopharmaceutical produced by Recombinant DNA Technology (except insulin). a. What is the name of the drug/trademark?b. Write its mode of action.c. List the experimental steps under the laboratory conditionsd. List the production steps in the factoryIn order to manufacture insulin for patients with diabetes, scientists create recombinant DNA by inserting a human insulin gene into bacterial DNA and have the bacteria produce human insulin. Based on what you have learned in this unit about gene expression, what must the scientists do to the DNA sequence of the human insulin gene BEFORE inserting it into the bacteria, in order to have them produce the same insulin sequence that humans would produce? Explain.Which among the following statements is not true about mutations? * a.) It may either occur at the chromosomes or at the sequence of nucleic acids. b.) It is caused either by mutagens or through hereditary genes. c.) All mutations cause diseases and disorders in the developing organism. d.) All mutations causes a change in the structure or sequence of the genetic material.
- DNA is the blueprint for the cell, but not all genes in DNA lead to protein. Gene expression is the study of how genes are used to make their particular product. What are some examples of gene products that do not lead to proteins? (a) DNA can lead to carbohydrates. (b) can lead to phospholipids. (c) DNA can lead to lipids. (d) DNA can lead to RNAs which don't go on to be translated into protein.Suppose that you are hired by a biotechnology firm to produce a strain of giant fruit flies by using recombinant DNA technology so that genetics students will not be forced to strain their eyes when looking at tiny flies. You go to the library and learn that growth in fruit flies is normally inhibited by a hormone called shorty substance P (SSP). You decide that you can produce giant fruit flies if you can somehow turn off the production of SSP. Shorty substance P is synthesized from a compound called XSP in a single-step reaction catalyzed by the enzyme runtase: A researcher has already isolated cDNA for runtase and has sequenced it, but the location of the runtase gene in the Drosophila genome is unknown. In attempting to devise a strategy for turning off the production of SSP using standard recombinant DNA techniques, you discover that deleting, inactivating, or otherwise mutating this DNA sequence in Drosophila turns out to be extremely difficult. Therefore, you must restrict your…Bt crops contain a gene leading to production of a toxin that kills herbivorous insects that consume it. How are Bt crops created?a. by inducing plants to produce vitamin B and phytateb. by activating a cell surface receptor for Bt in bacteriac. by inserting a gene for glyphosate resistanced. by inserting a gene from Bacillus thuringiensis

The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve energy. d. The reason is conservation of energy for the enzyme. e.
