Answer:
<u>S- phase replication.</u>
Explanation:
Genetic material present within DNA molecules regulates cell growth, proliferation, and cell repair. The long-chain helical macromolecules of these deoxyribonucleic acids are formed from complex sequences called nucleotides; these four monomers are joined by strong covalent bonds (adenine, cytosine, guanine, thymine).
DNA coding regions are called genes-they hold the cell's basic instructions. Multiple nucleotides and even several chromosomes may contain genes. Typically, gene expression entails transcription into RNA, and translation into amino acids/ proteins. In the S phase of the cell cycle, DNA is copied by polymerases. Here, the chromosomes are unwound and DNA is copied during replication to produce identical strands.
Answer:
Option A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.

The properties of matter depend on which atoms are used and how they are bonded.
