GEL ELECTROPHORESIS What is the purpose of gel electrophoresis? During electrophoresis, do the DNA fragments move toward the (+) or (-) end of the gel? What does this indicate about the charge of the DNA molecule? Which size DNA fragments move the furthest through the gel? 4. What is the purpose of staining the gel?
Can somone check my answers are in bold please for both questions :Which is NOT true of the different conformations of DNA? A. Z-DNA is a left-handed spiral. B. Both A-DNA and B-DNA are dehydrated. C. A-DNA and B-DNA are right-handed spirals. D. A-DNA and Z-DNA segments are limited to short regions of DNA. For double-stranded DNA, consider the following base ratios: A/G C/T C/G (A+C)/(G+T) (A+G)/(C+T) (A+T)/(G+C) Which of those ratios always equals 1? A. 3, 4, and 5 B. 3 and 6 C. 1, 4, and 5 D. 4 and 6 E. 1 and 2
Questions are talking about amplification of DNA When we run the gel, we also run a ladder why? what information does that give us. why does it form a ladder shape on the gel (what is happening to cause things to separate out in many bands)?
Gel Electrophoresis Background and Protocol: Gel electrophoresis is a laboratory technique that separates molecules by size using an electric current. The test has a positive and negative side. Do you believe DNA should be loaded on the positive (red) side or the negative (black) side? Please explain why using scientific reasoning. Will larger DNA bands be closer or farther away from the well where you administered samples? Why?
May you please help me with this? A sample of purified DNA was incubated with deoxyribonuclease (DNAse) at 37oC. An aliquot was removed from the reaction mixture every minute for 5 minutes and the A260 recorded. The following data were obtained. Time (min) A260 0 0.60 1 0.64 2 0.67 3 0.70 4 0.72 5 0.73 Describe the action of deoxyribonuclease on DNA and explain the increase in A260.
Similarities between DNA agarose gels and SDS-PAGE are: Both methods use agarose gels. Both methods use electrical charge differences to separate molecules by size. Both methods determine the size of DNA fragments. All the given answers.
Show all work. 1. A) Produce a double-stranded piece of DNA that is 11 base pairs long using the letters A, C, G, T and label the ends of both strands using 3' and 5' appropriately. B) Calculate the ratio of (A+T)/(G+C) and (A+G)/(C+T). Explain why one ratio will always be equal to 1.0?
During gel electrophoresis, DNA molecules can easily be separated according to size because all DNA molecules have the same charge-to-mass ratio and the same shape (long rod). Would you expect RNA molecules to behave in the same manner as DNA during gel electrophoresis? Why or why not?
Which statements are true? Explain why or why not.1 Because the DNA double helix is only 2 nm wide—well below the limit of resolution of the light microscope—it is impossible to see chromosomes in living cells withoutspecial stains.2 A fluorescent molecule, having absorbed a singlephoton of light at one wavelength, always emits it at a longer wavelength.
Gel Electrophoresis is used often in forensics. Look at the following gel to the left. From the evidence DNA, which individual matches the DNA evidence left at the crime scene?
Gel electrophoresis drives DNA along an electrical current from a negative electrode to a positive electrode. This is because DNA is a negatively charged molecule. Do you think that gel electrophoresis would function differently if DNA was positively charged? How so? Why?
Please help me make an abstract using the information below it is the result and discussion of the experiment, the abstract should contain 150 words. THANK YOU! In the laboratory, the researchers identified the parts of the DNA and RNA structure. DNA structures compose of a nitrogenous base, the base pair joined by hydrogen bonds, a deoxyribose sugar, and a phosphate group. The deoxyribose sugar attaches to a phosphate group to form the double-helix backbone of the DNA. On the other hand, the deoxyribose sugar is attached to either one of the four nitrogenous bases. These are either the purines (adenine or guanine) containing two carbon-nitrogen rings and four nitrogen atoms or the pyrimidines (cytosine or thymine) containing one carbon-nitrogen ring and two nitrogen atoms (Purines vs. pyrimidines, 2022). Each purine is paired with a pyrimidine resulting in an equal total number for each as stated by Chargaff’s rule. Each pair is called the base pair joined by a weak hydrogen bond…
