Question

41. Which of the following is the correct order of the levels of DNA packaging in eukaryotic chromosomes? A) nucleosome chromatin fiber looped domainsheterochromatin B) nucleosomelooped domains chromatin fiber-heterochromatin C) heterochromatinnucleosomechromatin fiber looped domains D) chromatin fiber-heterochromatinnucleosomelooped domains E) chromatin fiber ? nucleosome ? looped domains ? heterochromatin uclear membrane functions as a 42. The n A) means of separating nuclear and cytoplasmic constituents. B) means of localization of the chromosomes within the cell. C) selective barrier, allowing certain substances in or out. D) means of sequestering many of the mRNA processing activities from the cytosol E) all of the above 43. You are using genetic engineering to design a protein that needs to be synthesized in the cytoplasm and then localized in the nucleus of the cell. To accomplish this, one could add A) a nuclear localization signal into the DNA that will be present in the mature protein. B) the compound during mitosis, at a time when the nuclear membrane is dispersed. C) a nucleotide or few nucleotides to the protein. D) a series of specific polysaccharides to the carboxyterminal end of the protein. E) all of the above
