- In general, which part of a DNA sequence will have the best quality? (Ex. Beginning, middle, end?) Why?What does the symbol “N” indicate (see the arrow)? Is this a problem for getting an accurate DNA sequence? The height of the peak in the figure is an indication of the quality of the data, with a high peak correlated with a low error in “base-calling” of perhaps 1 error in 10,000 bases. Is this generally a high-quality DNA sequence for determining the true DNA sequence of the gene studied? How can you tell? Which end of the sequence shown above is the 5’ end of the sequence being made via PCR.Which one of the following options would be a good way to identify the location of the poly A tail in the published DNA sequence for a gene? Look for AATAAA near the 3’ UTR of the DNA sequence. Look for TTTTTTTTTTTTTT… (many Ts) near the 3’ UTR of the DNA sequence. Look for AAAAAAAAAAA… (many As) near the 3’ UTR of the DNA sequence. Look for a stop codon.
- (Practice Hint: Click on the right-hand column to choose a bar height. Click again to change the bar height. Click the oraser button to start over.) A scientist analyzed a sample of DNA and leamed that it contained 15 adenine molecules. Predict, based on this information, how many thymine molecules were also in the analyzed sample. 0 molecules 15 molecules 30 molecules 45 molecules ? Amounts of Adenine and Thymine in Sample 10 5 0 adenine thymineThe genome of a typical bacterium contains about 5 x 106 base pairs, and can be replicated in about 30 minutes. The human genome is 600 times larger (3 × 10° base pairs), and at the rate of a bacterium, it would require 300 hours (~12 days) to be replicated; yet the entire human genome can be replicated within several hours. How is this possible?The illumina method of sequencing uses a unique type of nucleotide building block. What is the specific characteristic of this type of nucleotide that is important for this method of sequencing? How is the sequence of a fragment of DNA determined using this method?

- if You have been transported to a DNA Lab by a mad scientist. The scientist hands you a gel electrophoresis rig and he tells you to put the anode (+) and the cathode (-) on the rig correctly or... else. You have never run an electrophoresis rig in your life, nor do you know exactly what it does. However, you should be able to save your life knowing what you know about DNA. The DNA is loaded on the top of the machine and the DNA has to travel to the bottom. The machine has two metal pins, one on the bottom and one on the top. One pin can hold either an anode or a cathode, but not both. What makes sense to connect to the bottom of the anode or the cathode to get the DNA to travel in that direction? (the top will be the opposite) What is your reasoning?What is a DNA library? Do you think this name is appropriate?Examine the sequence for the DNA fragment below. Your job is to design primers for PCR that would be able to amplify this entire DNA fragment. Your answer must fulfill the following criteria: Design the primers so that they are each 7 bases in length. Please write out the sequence of these primers. Don’t forget to indicate the direction (polarity) of both ends of each primer. Note that only the polarity of one end of one of the template strands of DNA is provided below. Describe where the primer would bind (i.e. top or bottom template strand, left or right side of the DNA strand) Organize your response so that each primer, and associated information, is separated by at least one blank line
- 2) A scientist wants to increase the amount of sample of a DNA sequence of 100 bps. Calculate the number cycles of PCR required to generate 1 ng of DNA, when starting from a single copy. Note that the molar mass of an average DNA bp is 600 g/mol.A DNA synthesizer “machine” is used to create short single stranded DNA of any given sequence. You have used the machine to create the following the DNA molecules: (DNA #1) 5’- CTACTACGGATCGGG – 3’ (DNA #2) 5’- CCAGTCCCGATCCGT – 3’ (DNA #3) 5’-AGTAGCCAGTGGGGAAAAACCCCACTGG-3’ Now you add the DNA molecules either singly or in combination to reaction tubes containing DNA polymerase, dATP, dCTP, dGTP, and dTTP in a buffered solution that allows DNA polymerase to function. For each of the reaction tubes, indicate whether DNA polymerase will synthesize any new DNA molecules, and if so, write the sequence(s) of any such DNAs. DNA #1 plus DNA #3 DNA #2 plus DNA #3 DNA #1 plus DNA #2 DNA #3 onlyTo be able to properly analyze a sample of DNA, you need to have at least 1 µg of the DNA of interest. Assumptions: PCR is run with 30 cycles; Molecular weight per nucleotide in DNA is about 660 g/bp (330 g/bp for single stranded DNA or RNA); bp = base pair. a. Given that you can use the Polymerase Chain Reaction (PCR) to amplify DNA from the original sample and the size of the fragment to be amplified is 10,000 nucleotides long, estimate how many DNA molecules you need to obtain the minimum amount required to analyze the sample. b. Suggest a way to increase your sensitivity, i.e. amplify the DNA starting from even fewer molecules of template DNA.
