Assume liver and kidney tissues from the same mouse each contain about 10,000 species of cytosolic mrna, but only about 25% of these are common to the two tissues. suggest an experimental approach that might be used to establish that some of the mrna molecules are common to both tissues, but others are not. select all that apply. -southern blotting could be used to measure the fraction of common mrna molecules. -common mrna could be measured using the yeast two-hybrid system. -northern blotting could be used to measure the fraction of common mrna molecules. -dna microarrays could be used to compare the mrnas produced in the two tissues. -common mrna could be measured using nuclear run-on transcription.

Which part of cellular respiration must occur before any of the other steps can occur

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
