Why is Agrobacterium tumefaciens used to make transgenic plants? What is unique about this bacteria?
Homework Answers
Agrobacterium tumefaciens is a gram-negative bacterium mostly found in soil. It is used for plant transformation by the transfer of the tumor-inducing plasmid generally referred to as Ti plasmid to the host cells. It has the ability to integrate itself into the plant DNA and is where it also gets expressed.

1. The protein has been used to increase insect-resistance in plants. What is the origin of the Bt protein? a. European corn borer b. Agrobacterium c. Transgenic Bt corn d. Bacillus thuringiensis 2. When ingested, the Bt protein is not toxic to humans because: a. Humans produce antibodies against Bt b. Human saliva breaks down the Bt toxin c. The human blood circulatory system gets rid of the Bt toxic d. Humans do not have Bt receptors in their digestive...

9 , What feature of eukeryotic cytoplasmic membranes differentiates it the most from prokaryotic cytoplasmic membranes? Prokeryotic cytoplesmic membranes do not contain phospholipids. The composition of the phospholipid layer facing the outside of the cell is significently different compared to the lipid layer facing the cytoplesm. Unique proteins penetreting the cytoplesmic membrane. (Hint are there unique cytoplasmic membrane-protein differences found in eukeryotic cells?) Eukaryotic cytoplasmic membranes do not contain phospholipids Staphylococcus species can be distinguished from Streptococcus, Enterococcus, and Lactococcus...

Recently an antibiotic resistant strain of bacteria was found to possess a plasmid containing a unique drug resistance gene. Scientists and physicians are extremely concerned about this discovery since this drug resistance gene is usually only found as a part of the bacterial chromosome (nucleoid). In 1 bullet point --Explain the differences between chromosomal DNA (nucleoid) and plasmids. In 2 bullet points -- Explain why the medical community is so concerned about the the discovery of this particular antibiotic resistant...

1. Descri be the process of a bacterial transformation. Explain how scientists can make bacteria take up DNA in a laboratory setting. (15 pts.) 2. Genetic transformations are not limited to bacteria. There are real-world applications where scientists have taken genes from one organism and inserted them into another organism. Give an example of how a genetically modified organism (can be any organ- ism, you are not limited to bacteria) have been used to solve real-world issues. Describe the organisms...

a. Write a unique prediction about a factor that could increase alcohol fermentation. Why do you think that this factor could increase alcohol production? b. Write a unique prediction about a factor that could decrease alcohol fermentation. Why do you think that this factor could decrease alcohol production? (Choose a different factor to answer this question than the factor you used to answer the previous question.)
