Draw the hydrogen bonds between the bases. The letter R represents the rest of the nucleotide. The bases are positioned approximately as they would be in a DNA double helix. To indicate a hydrogen bond, simply draw a regular single bond between the atoms. Be careful not to modify the existing atoms or bonds in any way, nor add extraneous atoms or bonds. Draw the hydrogen bond(s) between thymine and adenine. Draw the hydrogen bond(s) between guanine and cytosine.

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
