You are studying a new gene “X” that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xf?? bp

A fellow lab worker brings you DNA containing what might be a similar gene in Leopard Geckos (XG). She asks you to see if you can amplify it using the same primers you used in frogs and the Bearded Dragon. You run the PCR and then analyze the product by…
If you had the ability to do gene editing with ONE gene for the betterment of human kind, which one would you choose, and why? Assume you could either change an abnormal allele associated with a disease, such as the cystin gene associated with Cystic Fibrosis to its normal wild type, or add a pre-existing human allele to a genome.
You are using the restriction enzyme HAEIII to digest different samples of the taster gene isolated from cheek cells of different people and amplified by PCR. When viewing the bands on the electrophoresis gel, one would expect that a taster (homozygote) would have---------band(s), whereas a carrier (heterozygote) would show--------band(s), and a non-taster would show------band(s).
You would like to amplify the gene shown here using PCR. Assume the primer to the 5' end of the gene sequence shown has already been designed. You need to design a primer to hybridize with the sequence on the right side of the diagram. What will be the sequence of the primer? 5’ —GENE——AATTGGCG 3’ a) 3’ CGCCAATT 5’ b) 5’ GCGGTTAA 3’ c) 5’ CGCCAATT 3’ d) 5’ TTAACCGC 3’ e) 5’ AATTGGCG 3’
You would like to amplify the gene shown below using PCR. What is the sequence of the primer you would generate for the left side of the sequence? a) 5’ GCGGTTAA 3’ b) 5’ CGCCAATT 3’ c) 5’ TTAACCGC 3’ d) 5’ AATTGGCG 3’
You learned in the chapter that an STR locus is a locus where alleles differ in the number of copies of a short, tandemly repeated DNA sequence. PCR is used to determine the number of alleles present, as shown by the size of the DNA fragment amplified. In the Figure below are the results of PCR analysis for STR alleles at a locus where the repeat unit length is 9 bp, and alleles are known that have 5 to 11 copies of the repeat. Given the STR alleles present in the adults, state whether each of the four juveniles could or could not be an off-spring of those two adults. Explain your answers.

You are an expert molecular biologist and you just had your regular PCR run and you are now checking your PCR products if you have amplified the correct desired DNA fragment. Upon checking the results of the electrophoresis, you noticed that you have several bands in your gel. You expected that you will only have a band with the same size as with the "X" size of the DNA ladder. Unfortunately, you have also seen bands that fall in the "W", "Y" and "Z" markers of the ladder. Assume you got a very high quality DNA template from your extraction step. A. What do you think are the possible causes of this incident? Explain briefly.
You’re working in a research lab, and your current task is to clone the gene that codes for tyrosinase from potatoes. You grind up some potato, extracts the DNA from it and digests the DNA with two different restriction enzymes (separately, not together): EcoRI and BamHI. You then obtain the cloning vector, pUC19, and digest it with the same two enzymes. You then run a gel which is shown to the right. You mix the potato DNA (digested with the enzyme you specified in part B) with cloning vector DNA (digested with the same enzyme). You then add the mixture to E. coli cells and carry out a transformation procedure so that the cells can each update a plasmid. You then plate the cells on a plate containing antibiotic. What antibiotic would be in the plate? Why would there be antibiotic in the plate? Be specific! Unfortunately, you don’t get a single bacterial colony to grow on the plate. Not even one! You review your procedure and realize that when mixing the digested potato DNA…
