Question 4-12 points Biologists use gel electrophoresis to sont DNA segments by size. DNA segments are...
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...
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 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:...
Question 5 The size of a piece of DNA can determine how fast or slow it travels during gel electrophoresis. True False Question 6 Radioactive probes attach to the complimentary base during some DNA lab processes. For instance a C would attach to a G and a T would attach to an A (nucleic acids). True False Question 7 How could/might all of this type of information at some point in time impact you personally (or your family members)? (Consider...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
What are the instruments that have been utilized for the review article discussions? ` 1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
