University of Illinois at Chicago Southern and Western Blot Samples Questions

Use this information to match the list of probes to the 3 samples below:You have isolated several DNA sequences from a variety of mouse tissues. You have labeled each one of them with a radioisotope and will use them as probes on blots of several DNA and RNA samples. Below are a list of all the probes you generated (probes A through E) and a list of all the DNA and RNA samples that you will analyze (Samples 1 through 3)Beside each sample, write the letters corresponding to all the probes that will bind to a complementary sequence in that sample. These responses are graded all or nothing!List of probesProbe A: promoter sequence of a gene that is only expressed in the nervous systemProbe B: promoter sequence of one of the genes encoding a ubiquitously expressed histone proteinProbe C: coding sequence of a gene that is only expressed in the nervous systemProbe D: coding sequence of one of the genes encoding a ubiquitously expressed histone proteinProbe E: intron of a gene that is only expressed in the nervous systemList of samplesSample 1: Southern blot of genomic DNA extracted from adult mouse cardiac muscle system cellsSample 2: Northern blot of mRNA extracted from adult mouse nervous system cellsSample 3: Northern blot of mRNA extracted from adult mouse cardiac muscle cells
