- A person can't see a single cotton thread for classrooms away. But if you wound thousands of them together into a rope, it'd be visible at the same distance. How is this statement an analogy to the DNA extraction of a strawberry?Which of the following best describes the process of DNA sequencing? a. DNA is separated on a gel, and the different bands are labeled with fluorescent nucleotides and scanned with a laser. b. A laser is used to fluorescently label the nucleotides present within the DNA, the DNA is run on a gel, and then the DNA is broken into fragments. c. Nucleotides are scanned with a laser and incorporated into the DNA that has been separated on a gel, and then the DNA is amplified with PCR. d. Fragments of DNA are produced in a reaction that labels them with any of four different fluorescent dyes, and the fragments then are run on a gel and scanned with a laser. e. DNA is broken down into its constituent nucleotides, and the nucleotides are then run on a gel and purified with a laser.Many times a forensic scientist has only a single hair or a single drop of blood for analysis. The amount of DNA in this kind of material is very tiny, and is not enough to use for comparison. In other words, running a single experiment to compare the DNA in a drop of blood with several suspects would use up all of the DNA in that drop of blood. This could be a serious problem if none of the suspects provided a match. How would a forensic scientist increase the amount of DNA available to them, starting with the DNA that would be found in their crime scene sample, such as a drop of blood from a suspect? PCR RFLPS Gel electrophoresis STRS
- When forensic experts work with a blood sample, what part of it do they use for PCR; red blood cells, white blood cells, or proteinaceous antibodies? If trying to find a tandem repeat segment, why would you pick one choice other another?Why were you able to see the DNA after adding the ethanol? What chemical process led to the visible masses of DNA? Why would some students have seen more DNA from their cheek cells at this step compared with other students?In your own understanding, answer the following: (No copy paste) Differentiate plane and section?
- 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 how electrophoresis separates DNA strands. How is a DNA fingerprinting test interpreted?A technician wants to amplify DNA from a patient sample. However, the lab is not equipped with a thermocycler. (i) (ii) Name two methods for DNA amplification that can be operated at constant temperature and give their acronyms. Explain these two methods in detail using a schematic and name all necessary components that are required to perform the amplification. Describe the main function of the middle ear. Highlight the role of the ossicles and the tympanic membrane.
