a. messenger rna (mrna)
b. enzymes
c. transfer rna (trna)
d. rna (hrna)

11. how do trna molecules know where to go?

16. true or false: after a protein sequence is made, it needs to fold into the correct shape.

17. the protein aquaporin must fold into what shape to work properly?
a. flat sheets
b. cube
c. cylindrical shape
d. none of the above

18. what is one characteristic that determines how the protein folds?
a. the amino acids hydrophobicity
b. the dna
c. the color of the amino acid

19. if all the amino acids were hydrophobic and you placed them in water, what would happen to the shape of the protein?
a. it would squish into a ball (as best as possible)
b. it would flatten out
c. half would flatten and half would be a ball
d. all the above

20. what is a mutation?
a. when something gets changed, or there is a mistake in the dna sequence
b. when the dna strand accidentally leaves the nucleus
c. when the mrna strand doesn’t attach to a ribosome
d. no protein forms

21. describe the effects a dna mutation could have on a protein.
a. the mutation might code for a different amino acid
b. it a letter is deleted it could shift the reading frame and change all the subsequent amino acids
c. a hydrophobic amino acid could change to a hydrophilic amino acid which would cause the protein to fold differently.
d. all the above

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
