Hello!
There are two possible answers to this. The one I'm assuming you're looking for is hydrogen bonds.
Hydrogen bonds are the bonds which hold together the double helix shape of DNA. These bonds result from a positive and negative charge drawing two molecules closer to each other. These bonds are generally seen as weak, however, since there are so many of these bonds (as there are so many nitrogenous bases in one strand of DNA), the double helix strand is fairly strong.
Hope this helps!
The correct answer is secondary structure of proteins is formed by the hydrogen bonding between amino acid chains.
Explanation:
The secondary structure of protein is generally stabilized by peptides bond along with hydrogen bonding between hydrogen atom and an electronegative atom such as oxygen.
The secondary structure both alpha helix and beta pleated sheet are stabilized by hydrogen bonding beside the presence of peptide bonds.

Ans.
A nerve is defined as a bundle of axons. Axons are slender, long projections protruded from neurons in PNS (peripheral nervous system). The nerves provide a pathway for the transmission of electrochemical nerve impulses from axons to the other peripheral body organs.
Thus, the correct option to be fill in the blank is 'bundle of axons.'
