Question
An effective DNA probe can sometimes be developed by knowing the amino acid sequence of the protein encoded by the gene. A student argued that this is too time-consuming since the complete amino acid sequence must be determined in order to create the probe. Does the student have a valid argument? Why or why not?

Use the results to answer these questions: a) Why does the Arabidopsis control generate two PCR bands, but the plasmid control only generates one PCR band? b) Did the negative control generate a PCR product? If so, what are the implications of this for the experiment? c) Would you use this nested PCR product from Shrimp Plant for cloning? Briefly explain your answerarrow_forward
- Can you help me with this question, please? What are the advantages of qPCR (RT-PCR) compared to conventional PCR? Choose all that apply a. human error is reduced as there are fewer human interactions with the samples b. you can visualize the results as the process is running c. samples can be compared as to the amount of template DNA in the original sample d. more samples can be run in a day by one personarrow_forwardDuring DNA isolation, you incubated the tissue sample at 55°C for 60 minutes, followed by incubation at 95°C for 10 minutes. What happens to the DNA molecules in this last 95°C incubation? What would happen to the PCR if this step was omitted?arrow_forwardYou have two samples you have to sequence: one is a cloned plasmid that you want to verify the sequence of, and another is the cDNA library of the transcriptome of a cell. Which method would you use for each sample and why?arrow_forward
- The current state-of-the-art in forensic DNA profiling involves the PCR-amplification and analysis ofshort tandem repeats, STRs, in the human genome. This approach has many distinct advantages.Please list and explain three of those advantages.arrow_forwardGive a detailed description of how probes are designed and arranged on a resequencing array. Your description should include the size (in base pairs) of the probe, where differences in sequence are located within the probe, and the types of experiments that would use this type of microarray.arrow_forwardUse this information to match the list of probes to the 3 samples below: You have isolated several DNA sequences from a variety of mouse tissues. You have labeled each one of them with a radioisotope and will use them as probes on blots of several DNA and RNA somples. Below are a list of all the probes you generated (probes A through E) and a list of all the DNA and RNA samples that you will analyze (Samples 1 through 3) Beside each sample, write the letters corresponding to oll the probes that will bind to a complementary sequence in that sample. These responses are graded all or nothing! List of probes Probe A: promoter sequence of a gene that is only expressed in the nervous system Probe B: promoter sequence of one of the genes encoding a ubiquitously expressed histone protein Probe C: coding sequence of a gene that is only expressed in the nervous system Probe D: coding sequence of one of the genes encoding a ubiquitously expressed histone protein Probe E: intron of a gene that is…arrow_forward
