The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)
Hope this was able to help you! I went through my answer and bolded the more important parts, and parts more useful for answering the question.
There are several ways to treat or cope with presbycusis (age-related hearing loss). Here are some of ways:
1. Hearing Aid(s)
2. Implants (Cochlea, Middle ear) - involves surgical operation
3. Lip reading or speech reading training
4. Hearing assistive devices - sound amplifying devices (cellphones, tablets, etc.)
It would be best to refer to an audiologist or otolaryngologist to for extensive diagnostic evaluation of the gravity of hearing loss and seek proper medical treatment.
