BMS 300 FINAL EXAM PRACTICE QUESTIONS (A+ GUARANTEED)

The anticodon on the tRNA for alanine is CGU and the anticodon for threonine is UGU. What is the base change that resulted in the SLC245A mutation? correct answers - cytosine to thymine The codons for arginine include CGA, CGC, CGG and CGU. what is the base change in the anticodon that results in the amino acid switch from the ancestral African form to the East Asian pattern of pigmentation from this mutation in the OCA2 gene? correct answers - uracil to cytosine from the passage, which of the following would you expect to be true for protein produced from the SLC245A gene? correct answers - would be glycosolated - span the plasma membrane - transported in vesicles on microtubules in the long bones of a 10 year old child, you would find chondrocytes in correct answers - hyaline cartilage of the articular surfaces of the bone - in the growth plates at the ends of the diaphysis given the information in the statement, the cellular process most compromised in I-cell disease is correct answers - glycoprotein modification from the statement, you can conclude that correct answers - material accumulated in the vacuoles is normally broken down in the lysosomes - the lysosomal enzymes are not properly targeted to the lysosome - phosphorylating sugars in the Golgi is necessary to target lysosomal enzymes properly in the accompanying diagram, the hormone would most likely be a ___, and affect cell function as a __ correct answers - derivative of cholesterol, transcription factor neurons in the hypothalamus secrete ___ hormones that are carried to the ___ in the ____ correct answers releasing hormones, anterior pituitary, hypothalamic-pituitary portal vasculature bones provides a readily available source of calcium stored as hydroxyapatite (calcium phosphate). cells in bone under control of peptide hormone parathyroid hormone convert hydroxyapatite to calcium and phosphate ions. the cells that are responsible for liberating Ca2+ from the hydroxyapatite are: correct answers - osteoclasts amino acids destined to be incorporated into protein arrive in the ribosomes covalently linked to correct answers - tRNA which of the following hormones is hydrophobic correct answers - cortisol and corticosterone
