Question
Chapter 12.1, Problem 2LO
Summary Introduction
To state: The questions that Griffith’s transformation experiment, Avery’s contribution to Griffith’s work, and the Hershey–Chase experiments had been addressed.
Introduction: DNA or deoxyribonucleic acid carries hereditary information from one generation to another. After several experiments, scientists have found evidence that claims that DNA is the hereditary material that passes on the genetic information from one generation to the next. DNA can be transferred through sexual or asexual reproduction. Proteins are products that are obtained from DNA after transcription and translation.

- What type of research is this? Explain.What do the results indicate? Their implications?https://opus.lib.uts.edu.au/bitstream/10453/31887/1/2012007630OK.pdfarrow_forwardPlease consider Figure 8.8 (attached below) in the textbook (Figure 8.7 in the 4TH edition), which contains data that were obtained by Clegg et al., is redepicted from their paper that was published in 1980, and for which information is provided on pp. 300-302 in the textbook (pp. 289-291 in the 4TH edition textbook); assess comprehensively the lowercase-Roman-numeral-labelled statements that appear immediately below; and click the uppercase-letter-labelled response that is presented below and conveys the most accurate information. i. At generation 0, the populations were characterised by D = -1 or D = 1.ii. The D value changes could have resulted from processes including crossing over during meiosis.iii. The D values changed by the factor (1- r) each generation.iv. At generation 0, the populations were characterised by D = -0.25 or D = 0.25.v. At generation 0, the populations were characterised by extreme values, representing complete linkage disequilibrium. Question 1 options:…arrow_forwardFollow these directions to access the entries for PTGS1 and PTGS2 in the “Gene” database at the NCBI Website:A. First, go to the NCBI homepage using the link on the lab webpage, or by going to: http://www.ncbi.nlm.nih.gov Select “Gene” from the database pulldown menu. Type “PTGS” in the search box, then click “Go.” Scan the results for the “Homo sapiens” entries. There should be one called “PTGS1” and one called “PTGS2.” Select each entry by clicking on its name, then read the paragraph under the “Summary” section for each entry. The drug Celebrex selectively inhibits PTGS2 while aspirin and other NSAID’s inhibit both PTGS1 and PTGS2 in the same way. Why do you think researchers wanted to discover a selective inhibitor to PTGS2? 2. Describe how studying 3-D structures of PTGS1 and PTGS2 could help researchers design a drug that binds to PTGS1, but not to PTGS2.arrow_forward
- In the Hershey–Chase experiment, the radioactive label 32P was present inside bacterial cells (i.e., in the pellet), whereas the radioactive label 35S waspresent outside bacterial cells (in the supernatant). What would the researchers have concluded had the reverse been true, that is, if the radioactive label 35S were inside the cells and the radioactive label 32P were outside the cells?arrow_forwardPlease answer the following questions using numbers and not text. For example, if you think the answer is 24, write 24 and not twenty-four. If you think the answer is 24 ATP, write only the number 24. As a microbiology technician, your job is to characterize a novel bacterial strain isolated from insects. Phenotypically, you have discovered that the new bacterial strain can grow in the presence or absence of oxygen. After genome sequencing and biochemical characterization, you know that your new organism is capable of making all of the enzymes necessary for glycolysis and the TCA cycle, and that it has an electron transport chain. Answer the following questions based on the growth of your organism on minimal media plates containing only acetate as a carbon and energy source. Acetate is transported across the membrane at the cost of 3 ATP per molecule. Each question should be answered based on the metabolism of one molecule of acetate. If you come up with a negative value, indicate an…arrow_forwardPLEASE ANSWER BOTH PARTS OF THE QUESTION a.) The Question on the image b.)

Crawford isolated and studied a series of mutations that affected several steps in the biosynthetic pathway leading to tryptophan in the bacterium Bacillus subtilis . Seven of the strains that they used in their study are listed here, along with the mutation found in each strain.Strain Mutation T3 T− 168 I− 168PT I− TI I− TII I− T8 A− H25 H− To map the genes for tryptophan synthesis, they carried out a series of transformation experiments on strains having different mutations and determined the percentage of recombinants among the transformed bacteria. Their results were as follows:(refer picture) On the basis of these two-point crosses, determine the order of the genes and the distances between them. Where more than one cross was completed for a pair of genes, average the recombination rates from the different crosses. Draw a map of the…arrow_forward
