The different types of RNA are found in the nucleus (during mRNA transcription) and in the cytoplasm (during protein synthesis).

Answer:
The correct option is C. Motor neuron does not fire action potentials
Explanation:
During contraction, the motor nerve passes down an action potential. A neuromuscular junction is formed by the motor neuron which stimulates the entry of calcium ions. The calcium ions bind to structures called as troponin which stimulates the binding of the filaments, actin and myosin. The filaments begin to contract by using ATP.
During relaxation, the action potential is stopped. Calcium is taken back into the sarcoplasmic reticulum. As a result, actin and myosin filaments do not link and hence, the contraction is stopped.
There will be a tall purple plant in result as when PT is crossed with pt, the dominant traits take over. Pp, Tp, Pt, Tt.
