I’m working on an unknown bacteirum project which i have to identify the name of bacterium. i already known that they are in corynebacterium species, and based on the list of possible bacterial unknown from my professor, it can be one of them:
1. corynebacterium glutamicum
2. corynebacterium pseudodiphtheriticum
3. corynebacterium xerosis
can you me with some methods to figure out differences between those bacteria? what test i should use to identify them? you.

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.
