- To prepare a sample for electrophoresis, samples of the DNA being investigated (a) are put into each of four tubes and induced to replicate (b). Also, into the first tube, an adenine terminator was added in addition to all the other nucleotides. As the complementary strand was being constructed, the terminators were occasionally incorporated wherever an adenine nucleotide was used. This random incorporation resulted in all possible lengths of DNA pieces that had an adenine on the end (c). The same process was conducted in the other tubes with thymine, guanine and cytosine terminators; one treatment for each of the four lanes in the gel. Electrophoresis separated the replicated pieces of DNA by size. Staining the gel revealed which lengths of the complementary DNA were terminated by which nucleotide terminators (d). The gel consists of four “lanes,” labeled A, T, G, and C, indicating either adenine, thymine, guanine, or cytosine terminated pieces of DNA. By “reading” down the gel, you…arrow_forwardA) Which molecule in the gel is the smallest - A, B, C, or D? Explain how you determined this. B) Identify one lane in this gel (1, 2, 3, 4, 5, 6, or 7) that shows evidence of DNase treatment. Explain how you determined this.arrow_forwardReferring to Figure 7-20, answer the following questions:a. What is the DNA polymerase I enzyme doing?b.

- Explain the principles behind DNA isolation using silica membrane spin column from Qiagen. 2 After DNA isolation using Qiagen extraction kit, the final flow through was subjected to spectrophotometric measurements. Explain the situation if the absorbances were found to be: i) The absorbance at 260 nm is higher than absorbance at 280 nm? ii) The absorbance at 230 is higher than absorbance at 260 nm?arrow_forwardThe DNA chromosome in E. coli contains approximately 4 million base pairs. The average gene contains about 1500 base pairs.

Why is the optimal annealing temperature vital in this technique? Explain how this temperature (too high or too low) will affect the efficiency of this reaction.

If you randomly shear E. coli DNA into 1000 bp fragments and put it through density gradient equilibrium centrifugation, you will find that all the DNA bands at the same place in the gradient, and if you graph the distribution of DNA fragments in the gradient you will get a single peak (see below). If you perform the same experiment with binturong DNA, you will find that a small fraction of the DNA fragments band separately in the gradient (at a different density) and give rise to a small "satellite" peak on a graph of the distribution of DNA fragments in the gradient (see below). Why do these two DNA samples give different results, when they're both 50% G-C? See graph B. B) If you denatured the random 1000 bp fragments of binturong DNA that you produced in question 1a by heating them to 95ºC, and then cooled them down to 60ºC and allowed them to reanneal, you would find that approximately 15% of the…arrow_forward
- What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes? List and discuss them.arrow_forwardA DNA strand was sequenced using the Sanger method (https://www.youtube.com/watch?v=KTstRrDTmWI). The reaction tube contained the DNA strand, fluorescently labelled dideoxynucleotide triphosphates (ddATP – yellow, ddGTP – green, ddCTP – blue, ddTTP - red), deoxynucleotide triphosphates, DNA polymerase, or its Klenow fragment.
