BMS 300 Exam (Already Graded A+)

The DNA in mitochondria would be expected to be correct answers circular Molecules called small nuclear proteins cut and splice pre mRNA molecules in the nucleus. The function of these molecules is to correct answers separate introns from externs in the pre mRNA molecule, cut out introns from the pre mRNA molecule, bring the end of one exon together with the beginning of the next exon, and increase the variability of the amino acids in a protein transcribed from a single gene Bisphosphonate is a drug commonly used to slow the progress of osteoporosis. It affects the chemistry of the hydroxyapatite in bone restoration. The cell type that you would expect to be inhibited by this drug is correct answers osteoclast Which of the following would you expect to lack glycosylated amino acids correct answers a steroid hormone receptor The amino acids in a single peptide are predominantly ____ and bind to a ____ correct answers hydrophobic, signal recognition particle Epidermolysis bulls is an inherited disease where keratinocytes separate from the dermis. You would expect that the mutations which cause this disease to be genes that encode for proteins found in the correct answers hemidesmosomes In the endocrine system, hormones are secreted in one region and have their effects on other cells. Which of the following is most important for determining the function of the hormone correct answers the availability of a receptor specific for the hormone Following a bad cut in the skin, a scar often forms. Upon microscopic examination, you find that the scar is composed mostly of collagen-like proteins covered by an epithelium. Based on this information you would expect that these proteins are correct answers extracellular proteins secreted by fibrocytes located in the dermis In patients with Addison's disease where cortisol levels are low because secretory cells in the adrenal cortex release little cortisol you would expect levels of corticotropin releasing hormone and the stimulation hormone to be ___ and ___ respectively correct answers high, high Tubulin and globular actin are cytoplasmic proteins that assemble into polymers. Both these polymers correct answers support plus end directed motors The amino acids that bind to the translocon in the endoplasmic reticulum are predominately correct answers hydrophobic In the lipid mosaic model of the biological membrane, transmembrane proteins span a phospholipid bilayer. Consistent with this model, you would expect a hydrophilic ion channel to be composed of correct answers alpha helices
