Dr. james isolated staphylococcus aureus, a type of bacteria, from the leg wound of a ten-year-old boy. he suspected these bacteria would grow better at body temperature than room temperature (72°f), but thought that he should collect data to support his thinking. dr. james introduced the same number of staphylococcus bacteria

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.
