Does chloramphenicol interfere with eukaryotic protein production? O Yes, chloramphenicol targets the large ribosomal subunit which is present in both prokaryotic and eukaryotic cells. O No, chloramphenicol targets the 50S ribosomal subunit which eukaryotic cells do not have. O Yes, chloramphenicol targets protein synthesis which is performed by both prokaryotic and eukaryotic cells O No, chloramphenicol targets cell wall synthesis which eukaryotic cells do not have

Your friend has discovered a protein that they suspect is glycosylated. They decide to perform a series of tests to determine the nature of the oligosaccharide. Assuming/Knowing the following: Fucose molecular weight is approximately 164 Galactose molecular weight is approximately 180 GalNAc molecular weight is approximately  221 Mannose molecular weight is approximately 180  Sialic Acid molecular weight is approximately 309 Neuraminidase cleaves before a Sialic Acid (Sialic Acid and anything after leaves the protein) Beta-galactosidase cleaves after a Galactose (Galactose and anything before remains on the protein) Peanut Agglutinin binds to GalNAc Concanavalin A binds to Mannose Hemagglutinin binds to Sialic Acid Based on preliminary results, they suspect that the oligosaccharide is 7 glycosides long and weighs a total of 1414 g/mol They carried out the following experiments: they treated the protein with either a glycosidase or a lectin, and then pelleted the protein using…

Peptide 1: QAMGRAGDLKYLGLHSV Peptide 2: ALMALFMVMALVLVSVLFIA Peptide 3: MVEDLLKQIARYLISE Which of these peptides would be most likely to be found as an a helix in a soluble (cytoplasmic) protein? Which would be most likely to be found as an a helix in a transmembrane protein? Which would be least likely to form an a helix of any kind? Briefly explain your answers.

What general structural feature is shared by proteins that specifically form homodimers (but not homotrimers, homoteramers etc)? Only one answer is correct.     the surface consists of hydrophilic alpha-helix.   the surface is highly modified by post-translational modification.   the surface is permanently bound by chaperones.   the surface is unstructured.   the surface, or part of it, is self-complementary.

What feature of RNA would allow it to function as a ribozyme? Why are there no naturally occurring DNA enzymes?

The primary complexes for protein synthesis and very long chain fatty acid degradation in eukaryotes are A O ribosomes and proteasomes O ribosomes and peroxisomes O proteases and lysosomes proteases and proteasomes O ribosomes and mRNA and respectively
