DNA fragments can be separated and identified by(gas chromatography, capillary electrophoresis).

Which of the following are necessary for Sanger sequencing? Select all correct answers. Group of answer choices ddNTPs an oligonucleotide primer DNA polymerase dNTPs DNA ligase a restriction enzyme

DNA evidence at a crime scene can be copied by theprocesses of the ___________ with the aid of a DNApolymerase and specific primers.

Gel Electrophoresis is used in many different forms to learn about DNA, RNA or proteins. Research one laboratory method or technique that uses DNA electrophoresis in order to learn more or make determinations about DNA, RNA or Proteins.  Name of technique or method Brief description of what the electrophoresis results are used for in the method. Include a link to your resources Include an image of the results or technique you describe

Select the correct terms: To work on removing PERV DNA from the pig genome, researchers first replicate the DNA many times, using (PCR / CRISPR). This process increases the amount of DNA so that they are able to run experiments to edit the genome, using (PCR / CRISPR).

Evaluate the gel provided below. Use the notes to help you read the gel: DNA is loaded in the wells (little pockets) at the top. The wells are the dark spaces under the numbers. DNA moves from the wells into the gel. The smaller the DNA the more quickly it moves. The samples on the ends are DNA ladders. We know the sizes of each of those bands and can use them to estimate the size of the DNA in the patient samples. 1 2 3 1: DNA ladder 2: Positive control 3: Patient 1 sample 4: Patient 2 sample 5: Patient 3 sample 6: Negative Control 7: DNA ladder 300 bp 100 bp 1. Why are positive and negative controls needed for PCR (or any test)? 2. Initially, test kits sent out by the CDC were flawed. The negative control sometimes showed up as positive. What misdiagnosis would potentially occur with this mistake? (Over or underdiagnosis?) 3. The CDC ultimately said to use the test anyway. Why might this be the case, given the current situation? 4. How would you evaluate the results above? Do any of…

Explain and evaluate the measures to protect patients and clinicians from radiation that are incorporated into the procedure for taking ordinary X-ray images. For this question you will need to look at: record keeping procedures • medical exposure control radiation safety infection control

Crime Scene Investigation: Cindy was attacked by a masked assailant but she managed to scratch him and get away. Three suspects were apprehended and their DNA samples were cut by the same restriction enzyme and then run through a gel. 1. Whose DNA matches the skin under Cindy's fingernails? 2. Why do some DNA pieces travel farther in the gel than others? 3. Why is important to use the same type ofrestriction enzyme when cutting all the DNA samples? Skin under Fingernails Cindy's DNA Suspect X II Suspect Y Suspect Z

A comparison of which molecule types will be most likely to include the molecules primarily responsible for cellular energy? A) proteins and lipids B) carbohydrates and lipids proteins and carbohydrates D) carbohydrates and nucleic acids Proteins and polysaccharides are polymers.
