3. Can you think of an example of a role that chemistry plays in each of these themes? a. emergent properties b. structure and function are related c. cell theory d. hereditary information is passed from one generation to the next in the form of DNA e, cells maintain a constant interior environment and interact with the exterior environment f. evolution 4. Using sickle cell disease, explain an example of each of the following themes in a biological system a. emergent properties b. structure and function are related c. cell theory d. hereditary information is passed from one generation to the next in the form of DNA e. cells maintain a constant interior environment and interact with the exterior environment f. evolutionExplanation / Answer
4)Answer-:hereditary information is passed from one generation to the next in the form of DNA
***This is an autosomal linked recessive traits that can be transmitted from parents to the offspring, when both the partner are carrier for the gene,The disease is controlled by a single pair of allele Hb^ and Hbs.out of three possible genotype only homozygous individual for Hbs show the diseased phenotype heterozygous(Hb^Hbs) individual appear apparently unaffected but they are carrier of the disease as there 50 probability of transmission of the mutant gene to the progeny,
The defects is caused by the substitution of the Glutamic acid by Valine at the sixth position of the beta globin chain of the HB molecule, The Substitution of amino acid in the globin protein results due to the single base substitution at the sixth Codon of the beta globin gene from GAG to GUG,
The mutant HB molecule undergoes polymerization under low oxyzen tension causing the change in shape of the RBC from biconcave Disc to elongated sickle like structure,
