- You are performing an experiment using CRISPR-cas9 to genetically modify the LacZ gene of a culture of E. coli. After you run the experiment, you decide to use gel electrophoresis to genotype the different bacterial cultures to determine if the gene editing was successful. How could your electrophoresis results confirm that the PCR was successful? And how could your electrophoresis results confirm that you successfully extracted genomic DNA from your bacterial samples?arrow_forwardWhat are the main differences between whole genome sequencing and whole exome sequencing?arrow_forwardCompare and contrast the use of PCR and gene cloning for amplifying DNA fragments. What are the advantages and disadvantages of each method?arrow_forward

- You are performing PCR for the first time using some new primers that are 25 nucleotides in length with an estimated melting temperature of 65 0C to amplify a 200 nucleotide gene. After PCR, you run an agarose gel on the samples and observe a faint band at 25 nucleotides. What is the best possible explanation for the results? The primers hybridized to multiple sites on the DNA template. Too much template DNA was added to the PCR mixture. The primers dimerized preventing DNA transcription from occurring. A nuclease was in the solution causing degradation of the DNA.arrow_forwardHow did the private corporation Celera Genomics approach the sequencing of the human genome? What was the advantage of this approach?arrow_forwardIn PCR, the size of the product is based on A) the position of the primers. B) the amount of DNA you add to the reaction. (c) the number of cycles the process has gone through. D) the amount of enzyme you add to the reaction. the location of the machine.arrow_forward
