- QUESTION 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 16 Match the definitions and key words with the group name (programmed or stochastic). From the drop down boxes, choose the correct letter (A -- Programmed or B -- Stochastic). Celluar Aging: suggesting that the lifespan of a species is determined by an internal cellular "clock" that limits the number of cell divisions. Immune System: suggesting that aging is due to a break-down in the body's natural defense system against bacteria, viruses, and other substances. Error Theory: suggesting that errors at the cellular level produce "faulty" molecules. Evolutionary theory: suggesting that aging is a natural way to limit the reproductive potential and timespan of members of a species. Wear and Tear: suggesting that like a battery or a machine, the human…Question- 1. In onions, male sterility is due to the interaction of a chromosomal allele pair hh and “sterile” (S) cytoplasm. All other combinations (i.e. HH/Hh and “sterile” cytoplasm, HH/Hh or hh “fertile” (F) cytoplasm) result in male-fertile plants. The male-sterile trait is incorporated into inbred lines to produce hybrid F1 seed on a commercial scale.a) How would you perpetuate the male-sterile line? Show the cross.b) Briefly outline the method of producing hybrid seed (heterozygote) for the commercial crop. Show the cross.c) Does it matter whether the cytoplasm is fertile or sterile in the male-fertile inbred? Explain.

To understand more about this cell line and how it is different from normal cells, some experiments on the cell cycle of the colon cancer line are carried out. The cells are examined under the phase contrast microscope and the length of mitosis was found to be 90 minutes. Next, a DNA marker is used to find out how long DNA synthesis takes and indicates that DNA synthesis takes 3 hours. There is a gap between DNA synthesis and mitosis of 3.5 hours and a gap between mitosis and DNA synthesis of 4 hours. What is the total length of the cell cycle? _____ hours?
