Question
Chapter 39.4, Problem 1EQ
Summary Introduction
To predict: The purpose of growing wild-type tomato-plants and genetically engineered tomato plants of the same age together for 3 weeks.
Introduction: The genetically modified crops are the plants whose genome has been slightly altered to provide benefit to the crops in terms of pest-resistance, enhanced nutritional value, and so on.

What is the purpose of the activity “Transgenic Manipulation?”
In the "Bacterial Transformation" experiment, why were there no fluorescence bacteria present in the other plates even though these were inserted by the +pGLO plasmid? (Note: Discuss the importance on the addition of ampicillin and arabinose to the medium of the genetically engineered bacteria). Limit your answer to 1-3 sentences only.
Comment on the failure of p1vir
transduction experiments and give a
reason why you think the transductions
was unsuccessful for some genes. Suggest
any alternative methods that could be used to
create the mutations that were unsuccessful in
these experiments?
There are no colonies on the plate for some of
the genes. and in DNA sequence, some
colonies don't have primers present. For PCR,
some colonies are not replaced by kanamycin
or tetracycline.

- Remember that although there are many interesting ideas about genetic engineering of plants and animals, this is specifically about GE bacteria. Please be sure you are answering the following questions: 1) What is the species that was modified, and what species did the introduced genes come from? 2) What is the purpose of the genetic engineering? What were people hoping to accomplish? 3) What are the benefits (or potential benefits) of the engineered bacterium? 4) What are the risks (or potential risks) of the engineered bacterium?arrow_forward1.) What characteristics of VNTR and STR make them useful for DNA fingerprinting? 2.) How does PCR minimize the problems associated with degraded DNA? 3.) What factors can cause DNA to become degraded? 4.) If Ethidium bromide was not added to a gel, what would happen? 5.) How can you tell if an individual is heterozygous for the D1S80 marker? 6.) If a negative control produces a band, what does this indicate? 7.) In an experiment, a student’s sample amplified for D1S80 produced 3 bands. It was the only DNA sample run on the gel. The student knows that there was no problem with the Thermocycler or primers because the other students in the class had the expected results of only one or two bands. What is the most likely explanation for these results?arrow_forwardThe temperature at which the primers and target DNA hybridize may be changed to influence the stringency of PCR amplification. What effect will changing the hybridization temperature have on the amplification? Let's say you have a certain yeast gene A and want to check whether it has a human equivalent. How might managing the hybridization's rigor benefit you?arrow_forward
- PLEASE CHECK THE WORDS THAT ARE IN BOLD. THEY ARE THE SAME QUESTIONS BUT THE WORDS IN BOLD ARE DIFFERENT. Assuming a linear piece of DNA (plasmid) was used as starting material, how many restriction sites were there considering you observed three bands after agarose gel electrophoresis.
