You are a baker with your own unique strain of baker's yeast

You are a baker with your own unique strain of baker's yeast species Saccharomyces cerevisiae. From a single colony of your yeast, you isolate genomic DNA and amplify the 18S ribosomal RNA gene by PCR. (The 18S gene is the eukaryotic equivalent of the prokaryotic 165 gene.) When you run the PCR products in an agarose gel, you find a single band of DNA. You observe a single band of DNA because: The PCR products have different DNA sequence but are all the same size The PCR products are different sizes but have the same DNA sequence The PCR products have the same DNA sequence and are all the same size The PCR products are different sizes and have different DNA sequences
