N-Acetylglucosamine II. fucose III. mannose IV. galactose I, II, IV only I, II, III only II, III, IV only I, II, III, IVQUESTION NO. 1 Cystic fibrosis is a frequent generic disease of Caucasians. The CF gene codes for a protein called the cystic fibrosis transmembrane conductance regulator (CFTR) which functions as a cAMP-regulated chloride channel. The protein has two membrane-spanning domains, two domains that interact with ATP, and one regulatory domain. The most common defect is in the gene for one of the ATP binding domains. The result is a protein that does not fold correctly in the endoplasmic reticulum, is not properly glycosylated, and is nor transported to the cell surface. Rather, it is degraded in the cytosol within proteasomes. Drugs that foster chaperone interaction with the mutant protein are a potential therapeutic approach. Chaperones A. are always required to direct the folding of proteins. B. when bound to protein increase the rate of protein degradation. C. usually bind to strongly hydrophilic regions of unfolded proteins. D. sometimes maintain proteins in an…question 24 DNA is a hereditary molecular that is composed of A Deoxyribose,phosphate, and nitrogen bases B Deoxyribose,a pentose, and nucleic acids C Sugar,proteins and thymine D Adenine, phosphate, and ribose

- Question 21>In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.What hypothesis was being tested in the initial experiment with open versus sealed jars?A.The type of meat used affects the likelihood of spontaneous generation.B.Spontaneous generation can occur only if meat is exposed to air.C.Spontaneous generation is more likely during the long days of summer.D.Maggots do not arise spontaneously, but from eggs laid by adult flies.QUESTION 10 A 48-year-old female patient has breast carcinoma and presents to the hospital outpatient unit complaining of low energy.
