Question

check Your Understanding 5. How does the mutated CFTR protein contribute to What is the difference between genetic engineering and cloning a. Genetic engineering is governed by an international cystic fibrosis? a. The mutation prevents the channel protein from moving chloride across the membrane, resulting in a thick, sticky mucus ethics committee. Cloning does not have any formal ethics oversight. b. The mutation prevents the channel protein from moving sodium across the membrane, resulting in a thick, sticky mucus b. Genetic engineering uses PCR and CRISPR.Cloning does not use PCR or CRISPR Genetic engineering focuses on changing an organism's genome, while cloning focuses on copying genetic material. c. The mutation causes the channel protein to produce the sticky, thick mucus. exa d. The mutation attracts more mucus to the channel protein. d. Genetic engineering refers to gene manipulation in humans.Cloning refers to gene manipulation in all 6. How is CRISPR used in genetic engineering? other species. a. to clone cells b. to cut DNA c. to insert foreign DNA in a chromosome d. to test for genetic conditions 2. Place the elements in order to model how mosquito populations can be controlled using genetic engineering. a. affected males and affected offspring die b. insertion of gene into mosquito embryo c. release of affected male mosquitos to the wild d. development of drug-dependency gene e. breeding of genetically modified mosquitoes f. affected males mate with wild females MAKE YOUR OWN STUDY GUIDE In your Evidence Notebook, design a study guide that supports the main ideas from this lesson 3. What would happen if a thermocycler malfunctioned during a PCR run and never heated the solution? a. The DNA polymerase used to separate the DNA Genetic engineering is used to solve many societal and environmental problems, but there are benefits and risks associated with genetic engineering strands would not be activated. b. The PCR would proceed at a slower rate c. The primers would not bind to the target DNA sites, The ethical considerations of doning and genetic enginee are complex. Scientists must balance scientific progress w the concerns of the public. and DNA synthesis would not occur. d. The DNA strands would never separate, and the PCR Remember to indude the following information in your study guide .Use examples that model main ideas. would never begin. 4. Which of the following is not a criterion for a disease being a good candidate for gene therapy? a. genetic information can be distributed to new cells b. biology is understood . genetic basis of disease is identified Record explanations for the phenomena you investigated Use evidence to support your explanations. Your support include drawings, data, graphs, laboratory condusions, a other evidence recorded throughout the lesson controlled by one gene up to a handful of genes e. none of the above onsider how genetics, engineering, technology, and influence and affect each other.

Answer 1

1. (C) Genetic engineering focuses on changing an organism's genome, while cloning focuses on exactly copying genetic material.

2. (E) Mosquito population can be controlled by the breeding of genetically modified mosquitoes.

3.(D) Thermocycler increases the temperature of the sample to denature the DNA so that the primers can anneal and Taq polymerase initiates DNA synthesis. Therefore, if thermocycler malfunctioned then the DNA strands would never separate, and the PCR would never begin.

4.(E) If a disease is controlled by more than one gene, then gene therapy will not be beneficial for that disease.

5.(A) The mutation prevents the channel protein from moving chloride across the membrane, resulting in thick, sticky mucus.

6. (C) CRISPR is a technique which is used by genetic engineers to edit the genome or a gene. Thus by using this technique, we can insert foreign DNA in a chromosome.
