Bоnus questiоn (2 pоints) You hаve recently been hired by а biotech compаny to study a frog gene, RAD1, which encodes a peptide found in the frog skin that renders the frog resistance to radiation. Your assignment is to clone the RAD1 gene and transform it into yeast for mass production. You proudly told your boss that you know how. Your boss gave you the primers and the RAD1 DNA template, and you set up the PCR reaction to amplify the RAD1 gene together with a yeast selectable marker. To your dismay, you only saw primer-dimer formation (refers to nonspecific amplification of your primer sequences), but not the target DNA, on your agarose gel. You clearly recall that you added the correct amount of PCR reagents in the correct order. Give an explanation of your failed PCR.
