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

Which of the following best describes the process of DNA sequencing? a. DNA is separated on a gel, and the different bands are labeled with fluorescent nucleotides and scanned with a laser. b. A laser is used to fluorescently label the nucleotides present within the DNA, the DNA is run on a gel, and then the DNA is broken into fragments. c. Nucleotides are scanned with a laser and incorporated into the DNA that has been separated on a gel, and then the DNA is amplified with PCR. d. Fragments of DNA are produced in a reaction that labels them with any of four different fluorescent dyes, and the fragments then are run on a gel and scanned with a laser. e. DNA is broken down into its constituent nucleotides, and the nucleotides are then run on a gel and purified with a laser.
What is the relationship between fluorescence intensity of a spot and the amount of DNA in a sample for a Virochip DNA microassay? From the following which is the best choice Less DNA results in greater fluorescene since the laser passes through he sample eaiser More DNA equals to more intense fluorescence since the DNA makes a layer to refelct the laser light More DNA equals to more intense fluorescence since of more dye on the DNA is fluorescene More DNA results in to more fluorescence since there's more DNA to be excted by the laser None of the above

Why is the company Qiagen has more refined DNA extraction steps than a normal Strawberry DNA extraction practical? Summary of Qiagen DNA extraction steps Add ATL buffer and grind with sample. Add 20 microliters of enzyme Proteinase K to degrade protein into a 1.5-2ml microcentrifuge tube. Add 200 microlitres AL lysis buffer, and mix by vortexing for 5–10 seconds, which breaks cell membrane allowing DNA to be released. Incubate the sample at 56 degrees for 10 minutes. Mix the cell lysate with 200 microlitres ethanol by pipetting it at the side of the microcentrifuge wall so DNA precipitates. The DNA forms a white layer and the remaining liquid is discarded. Pipet the mixture into DNeasy Mini spin column placed in a 2 ml collection tube. Centrifuge for a minute at 8000 rpm. Place the mini spin column into a 2 ml collection tube, add 500 µl Buffer AW1, and centrifuge for 1 min at 8000 rpm. Then add it to a new 2 ml collection tube (provided), add 500 µl Buffer AW1, and centrifuge for 1…
Select all the following statements that are correct regarding agarose gel electrophoresis and restriction digests. Group of answer choices A higher percentage of agarose is used to distinguish between smaller pieces of DNA DNA fragments run from the positive electrode (where they are loaded) to the negative electrode Buffer is poured into the electrophoresis chamber AFTER the DNA has been loaded into the lanes. Larger DNA fragments migrate more slowly than smaller DNA fragments Loading dye is added AFTER restriction digests have been completed.

You are provided with coiled DNA and plasmid DNA that you subject to gel electrophoresis. Draw this gel. Remember to indicate the direction in which your DNA is moving and also show any reference samples. Also remember to show all components of your gel. Exact fragment sizes are not important.
Why is it important to sequence positive clones derived from PCR cloning? Group of answer choices Errors could have been incorporated during restriction enzyme digestion and so it is important to verify that only the expected protein is produced. Errors could have been incorporated during plasmid DNA extraction and so it is important to verify that only the expected protein is produced. Errors could have been incorporated during PCR and so it is important to verify that only the expected protein is produced. Errors could have been incorporated during cloning and so it is important to verify that only the expected protein is produced.
DNA EXTRACTION Materials: knife 1 cup of fruit Table salt clean piece of cloth or strainer for filtering resealable bag dishwashing liquid 70% rubbing alcohol (chilled) shot glass (or any transparent and narrow container resembling a test tube) How to do the extraction: Before you begin, make sure you have chilled your alcohol in the freezer for at least 3 hours. Room temperature alcohol will not work nearly as well as cold alcohol. Place about 50 mL of alcohol in the freezer to chill it and take it out only when you’re going to need it. (The alcohol will not actually freeze.) 1. The first thing you will need is a sample. Since DNA is found in all living…

Question Image hown bele nallest? Q. A gel from gel electrophoresis is shown below. Which DNA fragment is the smallest? B. Direction of Travel
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.
