49. Which of the following pairs the correct process and location within the cell?

30. The pedigree above demonstrates the phenotypes of three generations of a family with an autosomal recessive disorder. If individual II3 has a baby with a male who is heterozygous for this trait, what is the probability that their child will have this disorder as well?

41. Using the provided graph, match the human digestive enzymes with their optimum pH. 

29. Eye pigment in a particular strain of fly is determined by two genes. An autosomal gene that controls the color of the pigments in the eye has two alleles: a dominant allele (R) that results in red eyes and a recessive allele (r) that results in sepia eyes. A sex-linked gene that controls the expression of the colored pigments also has two alleles: a dominant allele (T) that allows for expression of the colored pigments and a recessive allele (t) that does not allow for expression of the colored pigments. Individuals without a T allele will have white eyes regardless of the allele of other eye color genes. Which of the following represents a cross between a white-eyed female and a red-eyed male?  

39. You are studying a DNA gene with the sequence TAC CCG CGT . Based on the amino acid chart provided, what would your three amino acids be for this particular segment of the gene?

32. Match the cellular process with its type of regulation.

34. When crossing an organism that is homozygous recessive for a single trait with a heterozygote,   what is the chance of producing an offspring with the homozygous recessive phenotype?  

42. What is the importance of the hydrogen ion gradient in chemiosmosis of cellular respiration?

3. Which of the following is a correct monomer/polymer pairing?

23. Which of the following is a likely result from uncontrolled cell division in eukaryotic cells?
