Question 2. From mouse nerve cells you isolate the mouse Tau-gene-containing DNA fragment and hybridize it to the mRNA encoding Tau from the cytoplasm of the same cells. Describe what you see when you look at the molecules under the electron microscope. A. A double-stranded DNA-RNA hybrid with complete overlap of all the sequences. B. A partially double stranded DNA-RNA hybrid molecule containing regions of DNA-RNA overlap representing the mRNA exons, loops where there are introns and tails at the 5' and 3' ends. C. A partially double-stranded molecule containing regions of DNA-RNA overlap representing the mRNA introns, loops where there are introns and tails at the 5' and 3' ends. D. Regions of DNA-RNA overlap representing the mRNA exons and loops where there are introns with no tails at the 5' or 3' ends. E. Two distinct molecules with no overlapping regions.
