Textbook Question
Chapter 10, Problem 12TYK
SCIENTIFIC THINKING The success of an experiment often depends on choosing an appropriate organism to study. For example, Gregor Mendel was able to deduce the fundamental principles in genetics in part because of his choice of the pea plant. Reviewing Module 10.1, how did Hershey and Chase take advantage of the unique structural properties of bacteriophage T2 to determine the genetic material?

Archibald Garrod was an English physician who first proposed that genes encode enzymes. Like the work of Gregor Mendel , his discovery had little impact on his contemporaries and was not widely accepted until many years later. Why are important discoveries in science sometimes not accepted immediately? Why does it often take years before they are generally accepted by other scientists?

Explain what this statement means step by step!arrow_forwardTo create genetically modified organisms (often called GMOS) scientists directly manipulate the genes of an organism, often by inserting or deleting one or more genes. The inserted gene is usually from another species. The purpose of this manipulation is to give the target organism and its offspring a new trait that improves it in some way. The improvement might, for example, give the organism higher vitamin content. The process is called genetic engineering. 1. What are genetically modified organisms? 2. What is Genetic engineering?arrow_forward
- Discuss one current application of geneticsarrow_forwardDamien and Jessica are friends that are interested in proteomics. One day Damien and Jessica go to a proteomics lab to have their proteome (all proteins in body) analyzed. The analysis shows that there is a difference in one amino acid within each of their hemoglobin proteins. However, both of their hemoglobin proteins appear to be functioning properly. They both come to you and ask you the significance of this finding, what do you tell them? Should they be worried?

Which among the scenarios below are the benefits of using GMOs? I. Genetic engineering in food can be used to alter genes in crops leading to new diseases in pants. II. Genetic engineering in crops such as rice, corn and tomato can be used to obtain new strains with better nutritional qualities. III. Genetic engineering in food can be used to create totally the same substances such as proteins and other food nutrients. IV. Genetic engineering can be used to increase the immunity to diseases in plants leading to uncontrolled transfer of the resistance genes to the harmful pathogens. V. Genetic engineering can restrict the diversity in organisms. VI. Genetic engineering can be used to suppress negative traits in human like certain genetic diseases. a. II, III, IV and VI b.

A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results? A - The bacteria were not affected by the antibiotic. B - After being exposed to the antibiotic, the bacteria altered their DNA. C - A new species of bacteria emerged after the antibiotics were introduced. D - Random mutations led some bacteria to be resistant and, over time, they increased in the population.arrow_forward

In subsequent years, many exceptions to this hypothesis were noted. A molecule of hemoglobin fails to support this hypothesis for which of the following reasons? n eukaryotes, one gene can code form multiple isoforms of a polypeptide. The functional hemoglobin protein is made from multiple polypeptides. Not all enzymes are proteins. Not all genes encode proteins.arrow_forwardGenetic engineering has been used in many different ways, such as human growth hormone for the treatment of pituitary dwarfism (recombinant DNA) plants engineered to be resistant to herbicides and pests an “antifreeze” gene inserted into some Atlantic salmon and halibut pick one of the examples of genetic engineering listed above to expand on.
