- During agarose gel electrophoresis, why does DNA move through the gel when electric current is applied? because DNA is negatively charged because a charged chemical from the loading buffer is bound to the DNA because DNA is positively charged because DNA absorbs electricityAll of the following are examples of materials that are bound by your purifying medium during the DNA extraction process, except: O endoplasmic reticulum extraneous DNA O Calcium (Ca2+) O Iron (Fe2+) O Magnesium (Mg2+) O lipid membranesA DNA fragment with 450 bp will be closer to the top (negative pole) of an electrophoresis gel than one with 2,500 bp.True or false?
- what type of gel(in terms of material) can be more suitable for the electrophoresis of 500-1000bp DNA fragment and why?In DNA isolation techniques, a washing step is always done prior to the final resuspension. What is the purpose of this step? In DNA isolation from blood samples, why does the vial for blood storage contain EDTA? In the preparation for DNA isolation in plants, the plant source is refrigerated and ground prior to extraction. Why is this so? Why are DNA pellets air-dried before resuspension in buffer?Why was it necessary to mash the strawberries extensively with your hands? (hint: you wouldn’t have to do this step with an animal cells). Why do we treat the cells with soap when conducting DNA extraction? And why do we add salt when doing the DNA extraction?
- Discuss the use of gel electrophoresis for the separation of macromolecules (DNA, RNA and protein) of different sizes and topological forms. (Include the different recombinant DNA techniques that require gel electrophoresis)Discuss the use of gel electrophoresis for the separation of macromolecules (DNA, RNA and protein) of different sizes and topological forms. (Include in you answer the different recombinant DNA techniques that require gel electrophoresis)Both protein and DNA are run together in an isoelectric focusing (IEF) electrophoresis using the immobilised pH gradient (IPG) strip with pH range of 4-7. After the electrophoresis and staining, only ONE band is observed on the middle of the IPG strip. The band is a protein band. Briefly explain why only the protein band and NOT the DNA band appear on the IPG strip.
- Explain why we choose to use 1% agarose gel for Electrophoretic Analysis of DNA via Agarose gel ElectrophoresisOur PCR samples already contain loading dye, but sometimes this isn’t the case. If your samples didn’t already contain dye and you wanted to load your PCR sample onto an agarose gel, you’d need to add loading dye to the proper concentration. There is a 6X loading dye available for use; how many µl of this loading dye will you add to 10 µl of your sample so that it is at a 1X working concentration? Show your work.Three pieces of cut DNA were isolated using gel electrophoresis.The DNA that is the longest will be closest to the positive or negative electrode?
