Two mammals with the genotype CcEr are crossed. 'C' produces a thick coat of fur and is dominant to 'c', which produces a thin fur coat. 'E' produces brown eyes and is dominant to 'e', which produces red eyes. What fraction of offspring would you except to have both a thin fur coat and brown eyes?

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.
