When you use the centrifuge the second time with the alcohol, where does the DNA go?Group of answer choices It doesn't dissolve so it comes out of solution The DNA floats to the top of the tube The DNA spins to the bottom of the tube It mixes into the alcohol and clumps together
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
DNA fingerprinting uses a process called gel electrophoresis to separate the fragments of DNA. Once the DNA fragments are sorted, the pattern of bands can be analyzed. Gel Electrophoresis Procedure The smaller DNA fragments start to move away from the wells and the larger DNA fragments remain closer to the wells. An electric current is passed through the gel. DNA fragments are treated with a dye. A restriction endonuclease is added to the DNA. Using micropipettes, the DNA samples are added to the wells. DNA fingerprint is produced. DNA fragments are produced. The order in which a DNA fingerprint is produced using gel electrophoresis is Answer, Answer, Answer, Answer, Answer, Answer, and Answer.

Which of the following best describes the process of DNA seqencing. a. DNA is seperated on a gel and the different bands are labled with flouroscent nucleotides and scanned with a laser. b. A laser is used to flurorescently label the nucleotides present with in the DNA , the DNA is run on a gel and then the DNA is droken into fragments c. Nucleotides are scanned with a laser and incrprorated into the DNA that has been seperated on a gel and then DNA is amplified with PCR. d. fragments of DNA are produced in a reaction that lables them with any of four different fluroscent dyes and the fragmented then are run on a gel and scanned with laser e. DNA is broken down into its constituents nucleotides and the nucleotides are then run on a gel and purified with a laser
Which of the following is not true about microarrays? Group of answer choices A microarray is a glass slide with single-stranded DNA attached to it. A microarray is covered in spots, where each spot represents a different sequence that will be assessed in the experiment. A microarray can assess hundreds of thousands of variants simultaneously. The same microarray slide can be used either for DNA microarrays or RNA microarrays
