Question

If the genomic DNA copy of a gene, which contains four introns, is hybridized to its pre-mRNA, you would expect to see loop(s) in the electron microscope. If the genomic DNA copy of a gene, which contains two introns, is hybridized to its mature mRNA, you would expect to see A, R R loop(s) in the electron microscope (2pts). Save Question 19 (2 points) The A subunits of DNA polymerase III are responsible for proofreading, while the A subunits are responsible for synthesizing the daughter DNA strands (2pts). Save

Explanation / Answer

If the genomic DNA copy of a gene, which contains four introns, is hybridized to its pre-mRNA, you would expect to see zero (0) R loop(s) in the electron microscope. If the genomic DNA copy of a gene, which contains two introns, is hybridized to its mature mRNA, you would expect to see two R loop(s) in the electron microscope.

The DnaQ ( subunit) subunits of DNA polymerase III are responsible for proofreading, while the DnaE ( subunit) subunits are responsible for synthesizing the daughter DNA strands.
