If you mixed the mrna of a human gene with the genomic dna for the same gene and allowed the rna and dna to form a hybrid, what would you be likely to see in the electron microscope? your figure should include hybridization involving both dna strands (template and rna-iike) as well as the mrna.

Explanation:

A gene in the DNA has both exons and introns. Exons are the coding sequences that will remain in the mature mRNA, and introns are non-coding sequences that are spliced out and are not a part of the mature mRNA.

If you hybridize genomic DNA with a mature mRNA, in a microscope you'll probably see something like the figure I'm attaching. In A you can see a schematic diagram of the mRNA-DNA hybrid; the loops are single stranded DNA containing introns, that are not present in the mRNA and therefore remain unpaired.

In figure B you can see a real image of a mRNA-DNA hybrid and its interpertation below.

The hybridization involving both DNA strands would look like a perfect pairing, because both DNA strands contain complementary sequences of exons and introns.
