Do you think each of the following types of mutations would have very severe effects, mild effects, or no effect at all? a. nonsense mutations occurring in the sequences encoding amino acids near the n terminus of the protein b. nonsense mutations occurring in the sequences encoding amino acids near the c terminus of the protein c. frameshift mutations occurring in the sequences encoding amino acids near the n terminus of the protein d. frameshift mutations occurring in the sequences encoding amino acids near the c terminus of the protein e. silent mutations f. conservative missense mutations g. non-conservative missense mutations affecting the active site of the protein h. non-conservative missense mutations not in the active site of the protein

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.
