A thousand individuals were classified according to gender and whether or not they were color-blind. Among the 1000, 480 were males. Out of these males, 442 were normal. Overall there were 956 individuals who were normal. Develop a joint probability table for these data and test whether colorblindness is independent of sex at the 0.01 significance level. Show all steps. [5 marks]​

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
