Shown below is a game which is an electric circuit. The person playing the game should have a very steady hand. The thin wire loop is to be passed from one end of the curved wire to the other without the loop touching the wire. If the loop touches the curved wire, the bulb glows.
In this circuit the loop acts as a/an .Required to answer. Single choice.

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.
