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…
When gel electrophoresis is undertaken, one well always contains DNA-marker molecules. The purpose of these markers is to Question 30 options: help visualize the DNA indicate when the DC current is turned on serve as a guide to the length of the fragments in the other wells indicate when the DNA has completely crossed the gel serve as a channel for ethidium bromide
When gel electrophoresis is done correctly, which of these DNA molecules would move the least through the gel? Group of answer choices: 1000 bp molecules 6 Kbp molecules 3 Kbp molecules 2000 bp molecules
Examine the pGLO plasmid DNA solution with the UV lamp. Note your observations. Using a micropipettor, withdraw 10 ul of plasmid and mix it into the cell suspension of the +PGLO tube by pipetting up and down three times. Close the tube and return it to the rack on ice. Also close the -PGLO tube. Do not add plasmid DNA to the -pGLO tube. Why not?
During a typical gel electrophoresis set up (negative pole at the top), which DNA fragment would be nearest the top after separating the DNA fragments? 10 kb 100 kb 2,500 bp 2 bp
Which is the odd one out ? For the rest, explain the concept/process/technique they are involved with. DNA polymerase primers DNA RNA ddNTPs
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.

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
You digest 4 uL of plasmid DNA that is 50 ng/uL concetration in a total volume of 20 uL. You run 10 uL of the digest on teh gel. You then do a DNA purification protocol with a Zippy prep on the remaining digested DNA. You elute the DNA in a 25 uL. A 2 uL ssample has the concentration of 2 ng/uL. What is the DNA yield? YIELD = How much dna came out of the column/how much DNA was loaded onto the columnRemember to subtract amount of DNA run on gel from total digested DNA to get hw much DNA was loaded onto the columnAmount that came out of the column equals the volume of the eluted DNA times the concentration of the purified DNA
