- 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.Which of the following correctly describes a possible scenario during a run of gel electrophoresis with DNA samples?Why is ripe banana a better sample compared to an unripe banana for DNA extraction ?
- (b) Use a drawing to illustrate the principle of DNA gel electrophoresis. +If DNA is extracted from the juvenile leaves of mint plant. Then how to check the quantity and quality of the extracted DNA through gel electrophoresis. How to prepare 1% agarose gel for this purpose?K What is an example of positive feedback? sweating when you are hot increased respiration during exercise decreased blood glucose levels when insulin is released maintenance of blood pH levels labour contractions during birth
- 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?What are the characteristics of a high-quality DNA extract? What do you do to determine the quality of your DNA extracts?we done an experiment where we extracted the DNA from strawberry, grape, and peas. With the strawberries, we were able to find its DNA in the solution very easily because it was floating on the top. But for the grapes we were only able to see very small clumps which we weren't able to collect. And for the peas, we weren't able to see anything or collect any of their DNA. all I need is for help with the CER(claim, evidence, and reasoning) thank you!!
- Give the purpose of gel electrophoresis system. If larger DNA is loaded in the gel, what will be the movement of such DNA, how about is smaller DNA is loaded into the gel?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 electricityRecombinant DNA molecules are produced by incubating plasmids that have been broken open by a restriction enzyme together with DNA molecules containing complementary sticky ends in the presence of the enzyme ? 1) exonuclease 2) DNA connectase O 3) DNA ligase 4) DNA polymerase O 5) endonuclease
