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.
DNA and RNA
Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, deoxyribonucleic acid, is one of the natural components. Deoxyribonucleic acid is a double-stranded molecule. Watson and Crick postulated the double-stranded model of the helix. A deoxyribonucleic acid is a molecular group that carries and transmits genetic information from parents to offspring. All eukaryotic and prokaryotic cells are involved.
DNA as the Genetic Material
DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it as a genetic component. Certain organisms have different types of nucleic acids as their genetic material - DNA or RNA.
Genetics
The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents several diseases in a human being. Thus, genetics also creates an understanding of various medical conditions.
DNA Replication
The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.
![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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0073c3cb-592b-4bc6-9252-89c2535e6255%2F23547b62-9c73-46e6-b17c-2e7fd2cf14d3%2Fcws1k6o_processed.png&w=3840&q=75)
