Explain why a scientist might want to manipulate bacteria and force them to take up plasmids...
Which statement about gene cloning is false? A. Bacterial cells take up recombinant plasmids by transformation. B. Recombinant DNA molecules usually contain a DNA fragment inserted into a bacterial vector. C. To insert a gene of interest into a vector, the gene of interest and the vector must be digested with different restriction enzymes D. Transformed bacteria are plated onto media containing the appropriate antibiotic and only bacteria containing the plasmid with antibiotic resistance will grow.
dh5α is a “cloning strain.” It is used to grow up plasmids (extra-chromosomal DNA) you want to use for other experiments. Why would you use dh5α and not K12 for this? (Note: all cloning strains are Rec- for this reason)
what are excess reserves and why might a bank want to keep them as part of their assets?
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...
Visit the MIT OpenCourseWare website. Look for a course you might want to take. 1. What is the name of the course you selected? 2. What are the requirements or materials must you have to take the course? 3. Investigate the registration process, but do not sign up for the course. Is it easy to register? 4. What information is required? Use a search engine to search for MOOCs. 5. List industries AND users who might take advantage of a...

Give one reason why we might want to have every generation use up exactly the same amount of a resource. Why might we want earlier generations to use more? Why might we want to save some for future generations?
-A scientist is studying a mutant strain of bacteria that cannot
synthesize isoleucine. After placing them in different mediums with
different intermediates, she places some bacterial cells in a
medium with Intermediate C and they survive and produce isoleucine.
Please state which enzymes in this bacteria’s metabolic pathway are
functional and which ones are not.
-In a wild type strain of bacteria, she notices that when
isoleucine accumulates its production starts slowing down, what
type of regulation is this? Where...
Explain why someone might categorize a stand-up comedian as a performance artist.
UPM (A). What in vivo conditions might the bacteria experience to promote biofilm development? (B). Explain why growth of the bacteria in the presence of ethanol increases PIA/PNAG production and biofilm development? (C). What makes bacterial biofilms resistant to antibiotics and host immune responses? (D). What future strategies might be used to combat device related infections?
