Chapter 31.5, Problem 1TYK
Summary Introduction
Introduction:
Producing clones implies to producing the same or identical copies of an adult plant. Plant cloning is done by asexual propagation. It is a widely used and very successful process for creating a new plant’s life. Through this process, gardeners can easily reproduce copies of the mother plant.

this is an example of biotechnology: In order to increase the yield of oil from canola, research focused on ways to reduce competition from competitor weed plants. Weeds can be controlled by spraying with a herbicide that interferes with biological processes, like amino acid anabolic reactions, in the plant cells. A mutant of canola that is resistant to herbicides is sometimes grown in fields that are sprayed with the herbicide. The majority of canola in Canada, though, is genetically modified to be resistant to herbicides. also use the link: https://youtu.be/VS3kcwgIwm0
Question:
Evaluating Biotechnologies in Food Systems
As we practice being able to describe choices in Biology you will use this consolidation task to organize details about the advantages and disadvantages of biotechnologies. In an ideal world, all solutions to improving our food system would have no negative consequences. But issues in Biology involve the interaction of many different factors and changes in one…

True/False 31) The process by which an electrical charge is used to introduce DNA into a cell to produce a transgenic organism is called electroporation.Answer: 32) Reproductive cloning is used to produce large amounts of mammalian proteins from transgenic agricultural animals such as cattle.Answer: 33) In gene addition, homologous recombination is used to remove the original gene and replace it with the cloned gene.Answer: 34) All stem cells have the potential to differentiateAnswer: 35) A bone marrow transplant involves the transfer of multipotent stem cellsAnswer: 36) The fact that in mammalian systems multiple genes may compensate for the loss of a gene is called gene redundancy.Answer:
In yeast, you have sequenced a piece of wild-type DNA and it clearly contains a gene, but you do not know what gene it is. Therefore, to investigate further, you would like to find out its mutant phenotype. How would you use the cloned wild-type gene to do so? Show your experimental steps clearly

- In the early 1990s, Carolyn Napoli and her colleagues were working on petunias, attempting to genetically engineer a variety with dark purple petals by introducing numerous copies of a gene that encodes purple pigment in the flower petals . Their thinking was that extra copies of the gene would cause more purple pigment to be produced and would result in a petunia with an even darker hue of purple. However, much to their surprise, many of the plants carrying extra copies of the purple gene were completely white or had only patches of color. Molecular analysis revealed that the amount of mRNA produced by the purple gene was reduced 50-fold in the engineered plants compared with wild-type plants. Somehow, the introduction of extra copies of the purple gene silenced both the introduced copies and the plant’s own purple genes. Provide a possible explanation for how the introduction of numerous copies of the purple gene silenced all copies of the purple gene.arrow_forwardFigure 4 shows the hybridization process between plant P and Q. a) Determine the sterile hybrid plant and the fertile hybrid plant. b) What is process A? c) State the chromosome number for the fertile hybrid plant.arrow_forwardGenetic engineering of plants provides an opportunity to alter their properties or performance in order to improve upon their utility. Such technology may be used to modify the expression of genes already present in the plants, or to introduce new genes of other species with which the plant cannot be bred conventionally. In fact, humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. How has this technology created novel genetic information by specific alteration of cloned genes? (provide an example). Why do you think modern genetic engineering, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain. In your response provide a specific example from literature to describe the implications of this technology (good or bad).arrow_forward

Cloning is the process of creating a genetically identical copy of another individual. With Dolly, the first cloned mammal, an egg cell was removed from a donor (B) and the nucleus was removed from the egg cell. Then cells from a sheep's mammary gland were removed from a second donor (A). The nucleus of one of the cells from the mammary gland was fused with the enucleated egg cell using an electrical pulse. The fused cell underwent cell division and at the blastocyst stage was implanted into a surrogate mother sheep. The fused cell is cultured and is implanted as a multi-celled embryo.

The gene associated with the mut1 mutation is called COB1 (i.e. mutations in COB1 cause the mut1 phenotype.) The researcher extracts DNA and RNA from developing ears of wild type, mut1 and mut2 plants. From the DNA samples COB1 PCR primers are used to amplify the coding region of the COB1 gene (see DNA gel below). An RNA gel is used to examine the expression of COB1 all three plants (see RNA gel below). results in photo: Which of the following is TRUE about the COB1 gene. a. There is a deletion in the COB1 gene in the mut1 plants. b. COB1 is not transcribed in the mut2 plant. c. There is a deletion in the COB1 gene in the mut2 plants. d.

Research groups are now planning to use SCNT to resurrect these huge elephant- like mammals. No mammoth eggs have been recovered so far, so elephant eggs would be used instead. An elephant would also be the surrogate mother for the resulting embryo. The researchers may try a modified SCNT technique used to clone a mouse that had been dead and frozen for sixteen years. Ice crystals that form during freezing break up cell membranes, so cells from the frozen mouse were in bad shape. Their DNA was transferred into donor mouse eggs, and cells from the resulting embryos were fused with mouse stem cells. Four healthy clones were born from the hybrid embryos. What are some of the pros and cons of cloning an extinct animal?arrow_forward
