Answer:
The correct answer would be never due to the tilt of the earth.
When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
Translation of mRNA into a peptide occurs in sequences of 3 nucleotides called codons. Each codon codes for one amino acid. Therefore, as the ribosome reads the codon sequence, it recruits a t-RNA carrying the respective amino acid. A peptide bond is thereafter formed on the growing amino acid chain before the ribosome translocates to read the next codon. This continues until the ribosome reads a stop codon signaling the end of the peptide.
