Concept explainers
a.
To predict:
The possible outcome of Griffith’s experiment using the heat-killed pathogenic and heat killed nonpathogenic bacteria.
Introduction:
The transformation of the genetic material in bacteria was experimentally found out by the person named F. G. He was trying to make the vaccine that could cure pneumonia, which is caused by the bacteria Streptococcus pneumonia. There exist two different strains of this bacterium. One of the forms of the bacteria is known as the S (smooth) form. This strain of the bacteria is virulent and forms smooth colonies in the culture. The other form is the mutant form or the R (rough) form. This strain was non-virulent and forms a rough colony in the culture.
b.
To determine:
The possible outcome of Griffith’s experiment using the heat-killed pathogenic and live nonpathogenic in the presence of an enzyme that digests proteins (protease).

- Describe the experiment performed by FrederickGriffith showing the transformation of R cells (nonvirulent) into S cells (virulent) in a mouse model. Describe each control scenario and their significance.Then describe the experimental procedure (test scenario) and the final results and conclusion. Define any terms used and be specific and complete in your response.arrow_forwardAnswer each of the following questions correctly.(2-5 sentences only) A. How cloning and expression of certain genes allows for massive production of the desired product.(Give an specific example) For example: the cloning and expression of insulin in bacteria allows for the mass production of this necessary protein for use by diabetic patients. B. How PCR may be used for the detection of disease–causing pathogens in a population during COVID Pandemic. For example: It may be used to check if a patient has a COVID virus infection.arrow_forwardBelow, you can see a picture of an antimicrobial drug. Regarding semi-synthetic antimicrobial drug development to try to avoid development of antibiotic resistance, use 1 sentence to address what is the significance/value of the presence of the various R-groups (e.g. R4, R5, R6, etc.)?arrow_forward
- Describe and explain the difference in results if the serial dilution step of the T4 bacteriophage suspension inour experiment was skipped (i.e., all of Step #3 of the procedures was skipped)? _________________________Current EventsThe Johnson and Johnson COVID-19 vaccine consists of inactivated adenovirus that has been altered to containgenetic information encoding SARS-CoV-2 surface spike proteins. The virus targets and delivers this geneticinformation to the cells of our respiratory tract, which produce benign SARS-CoV-2 surface spike proteins butare effective for training our immune system to defend us against SARS-CoV-2.Based on this information and your knowledge of viruses in general, could T4 bacteriophage be used in place ofarrow_forwardCite the qualitative tests to characterize the products of RNA hydrolysis. Indicate the reagents involved in the process and indicate the positive result: A. Bial's test B.Murexide Testarrow_forwardIn the Avery, McLeod, McCarty Experiment where supernatant from heat killed, virulent S Strain pneumonia solutions were added to non-virulent R Strain pneumonia cell cultures and allowed to grow in liquid media (i.e., broth). In tubes where Protease was added to the supernatant prior to cell culture, what was the observed effect when plating and growing the S. pneumonia cells to solid media?
