The two DNA strands are held together by hydrogen bonding between the bases on the different strands; therefore, all the bases are on the <u>inside of the double helix</u>, and the sugar-phosphate backbones are on the <u>outside.</u>
<u></u>
The two strands are held collectively via hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Covalent bonds arise inside every linear strand and strongly bond the bases, sugars, and phosphate groups (each within each thing and between additives).
Hydrogen bonds occur among the two strands and contain a base from one strand with a base from the second in complementary pairing.

Answer:
The gene for the protein is turned on and off at different times.
Explanation:
The turning on and off of the gene is described as gene regulation. This process is important because it enables the cells to react quickly to the changes in the environment.
Note that , this process mostly occur at transcription level during gene expression , and help in determining the amount of protein made by a gene.
