Question
B. Please provide correct solution. Thank you. Which of the following compounds would be considered a nonpolar amino acid? The Pauly lab works on a single polypeptide that is 312 amino acids long. The enzyme adds a sugar to a hemicelluloso. A single amino acid change in this protein results in NO sugar being added to a hemicellulose in plants with this mutation. Based on this information alone, we can conclude that the altered protein exhibits altered primary structure; the quaternary structure is not altered altered primary structure; the secondary and tertiary structures are not altered altered primary structure and altered tertiary structure, the secondary structures may or may not be altered altered tertiary structure, the primary and secondary structures may or may not be altered altered quaternary structure The molecular formula for the amino acid glycine is C2H5O2N. What would be the molecular formula for a peptide consisting of ten glycine molecules? If a double stranded DNA sample were composed of 10% thymine, what would be the percentage of cytosine? 10 20 40 80 impossible to tell from the information given Which of the following statements about chloroplasts and mitochondria is FALSE? Both organelles are thought to originate from prokaryotes Both organelles can synthesize ATP using substrate-level phosphorylation Both organelles contain a membrane-bound electron transfer system Both organelles contain DNA Both organelles import some of their proteins from the cytosol Under which of the following conditions would you expect to find a cell with a predominance of free ribosomes? a cell that is secreting proteins a cell that is producing cytoplasmic proteins a cell that is actively synthesizing its endoplasmatic reticulum a cell that is digesting food vacuoles a cell that is actively producing a cell wall or extracellular matrixExplanation / Answer
10) Structure of nonpolar aminoacid (alanine) : Option A is correct.
11) The addition of sugar to hemicellulose by an enzyme results in altered tertiary structure but not the primary or secondary structures. This is because, the protein undergoes structural conformations to attain 3 dimensional folding in the tertiary structure. Hence, option D is correct.
12) The molecular formula of Glycine is C2H5O2N. The polypeptide containing 10 molecules of glycine have the molecular formula C20H50O20N10. Option A is correct.
13) If a double stranded DNA contains 10% of thymine, then Adenine would be 10%, cytosine would be 40% and Guanine would be 40% to make up total DNA to 100%. Hence, option C is correct.
14) The statement both organelles can synthesize ATP using substrate level phosphorylation is false. Because, mitochondrai synthesize ATP by oxidative phosphorylation. Hence, option B is correct.
15) In a cell secreting proteins is expected with predominance of free ribosomes. All other cells are involved in protein synthesis and the ribosomes are bound during protein synthesis. Option A is correct.
