computer algoritnm ose kinase is a highly conserved gene that is expressed by many species, both prokaryotic aryotic. The most closely related prokaryotic homolog of hexose kinase has a protein e in which 90% of the amino acids are identical to those of the human version of the gene. for sequence sir organisms, you disco arn more about their similarity at the DNA level, you obtain segments of the genomic DNA g for the hexose kinase gene in both humans and this prokaryotic species. After combining DNA samples, you heat them to denature the DNA strands and then allow them to cool and heal. Finally, you examine the DNA hybrids you obtain under the electron microscope. our analysis reveals that there are three different DNA hybrids in this sample, these can be below.

Please help!

Using a computer algorithm that searches for sequence similarities in other organisms, you discover that hexose kinase is a highly conserved gene that is expressed by many species, both prokaryotic and eukaryotic. The most closely related prokaryotic homolog of hexose kinase has a protein sequence in which 90% of the amino acids are identical to those of the human version of the gene. 3. To learn more about their similarity at the DNA level, you obtain segments of the genomic DNA coding for the hexose kinase gene in both humans and this prokaryotic species. After combining both DNA samples, you heat them to denature the DNA strands and then allow them to cool and reanneal. Finally, you examine the DNA hybrids you obtain under the electron microscope. 3a. Your analysis reveals that there are three different DNA hybrids in this sample, these can be seen below. You reason that one must belong to the prokaryotic species, one to the humans and the third arose when one strand from each species base paired. Identify the origin of the DNA in each one of the observed structures by circling the correct answers below Hybrid A top strand Hybrid B bottom strand Hybrid C Hybrid B is double stranded DNA from PROKARYOTE or HUMAN Hybrid C is double stranded DNA from PROKARYOTE or HUMAN The hybrid A top strand is DNA from PROKARYOTE or HUMAN The hybrid A bottom strand is DNA from PROKARYOTE or HUMAN 3b. In hybrid A what are the large loops seen on the top strand of DNA? What are the smaller loops seen on both strands of DNA? Explain your reasoning.
