Homozygous pea plants with round seeds are crossed to homozygous pea plants with wrinkled seeds. The F1 progeny undergo self-fertilization. A single round seed is chosen at random from the F2 progeny, and its DNA examined by electrophoresis as described in the text. What is the probability that the observed gel pattern will be B?

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.
