Refer to the picture included in question 7 for this question. Please explain how gel electrophoresis separates the DNA fragments that are produced by the Sanger technique. Include the following elements within your explanation (not necessarily in order of how you should place them in your answer):
electric current and charge
size of DNA molecules
DNA samples
gel
wells
and buffer solution.
Refer to the picture included in question 7 for this question. Please explain how gel electrophoresis...
Gel Electrophoresis of Amplified PCR Samples 9. What is Alu? 10. Why is Alu useful for studying human ancestry? 11. Why do the two possible PCR products from our lab differ in size by 300 base pairs? 12. Explain how gel electrophoresis separates DNA fragments 13. Fill in the table below. For each genotype, write how many DNA bands (fragments) you would expect to see in a gel, along with the size of each (n base pairs) Table 1. Predicted...
The picture above represents an agarose gel that was used to analyze plasmid DNA after it was cut with the restriction enzyme HindIll. The plasmid was incubated with Hindill until all of the available Hindlll cut sites were cut by HindIll. After running the sample on the gel, three bands were detected (Note that there are three wells shown at the top of the gel for loading samples, however, only the middle well was loaded with sample). Based on this...
Stuck answering the rest of these 3. Application of DNA gel electrophoresis. DNA gel electrophoresis is commonly used in determining familial relationships among individuals, for ex; to establish paternity of a child. This technique is called DNA fingerprinting. In this technique the DNA of parents and children is roughly chopped up into pieces and resolved on an agarose gel. The DNA ill resolve according to their sizes and create a pattern or a "fingerprint". The fingerprint of the child is...
can someone explain throughly on how to find a-c??? thanks!!! The following question will provide practice in interpreting and analyzing gel results. 5. You obtained the DNA electrophoresis gel below. Three samples of lambda phage DNA were digested with 3 different restriction enzymes and the digested DNA was applied to the gel in lane 4 and the bands were visualized. The Hind Ill digest was used as a molecular weight standard marker and produced 6 DNA fragments of known size:...
The picture to the right below is of an actual acrylamide gel that has undergone electrophoresis for DNA fingerprinting. The molecular weight ladder (marker) is on the left, and the sizes of the different marker bands are indicated. a. How do the bands that are lettered A, B, C, D and E look to you? Would you describe them as pretty clear and defined, blurry and hard to distinguish, or a combination? KD I 1 b. Do you think that...
Biologists use gel electrophoresis to sort DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively charged (with a charge of two electrons per base pair). When you “run the gel” you are generating an electric field by connecting anodes and cathodes at the ends of the gel. This causes the negatively charged DNA segments to move towards the positive electrode. After running the gel, smaller DNA segments have moved farther from the...
Question 4-12 points Biologists use gel electrophoresis to sont DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively chargod (with a charge of two electrons per base pair). When you "run the gel" you are generating an electric field by connecting anodes and cathodes at the ends of the gel This causes the negatively charged DNA segments to move towards the positive electrode. After nunning the gel, smaller DNA segments have moved...
DNA Electrophoresis: a) The DNA reaches terminal velocity quickly during electrophoresis and stays in that state. Solve for the terminal velocity for the viscous and drag force case. b) Which of these terminal velocities depend on the size of the DNA molecule? How does the terminal velocity change with molecule size? ( does terminal velocity go up or down as the size gets bigger?) c) Based on your calculations is the resistive force on a DNA molecule during electrophoresis best...
Can someone help me with this homework question on gel electrophoresis? Translocation and deletion 3. You PCR amplify a 500 bp (base pairs) piece of DNA that has diagnostic value in determining whether a patient has a mutation within a specific DNA region. You know that this DNA segment of the "normal" gene does not include an EcoRI restriction site; but the mutated DNA segment of the same gene contains an EcoRI restriction site due to a point mutation at...
Hi I have a problem with number 5, it involves gel analysis results. There are 2 parts, a,b,c. For A Im sure you need to make a graph with distance in (cm) on the vertical axis and log10 bp on the horitzontal. I need help figuring out where to start and what to do. Please help! The following question will provide practice in interpreting and analyzing gel results You obtained the DNA electrophoresis gel below. Three samples of lambda phage...
