It is difficult to obtain a final conclusion with this information, but it is possible that the sample doesn't contain living organisms whose genetic material is composed of DNA.

Medulla oblongata, the lowest part of the brain, is responsible for autonomic functions like ventilation, cardiac conduction, and vomiting.
The brain is a very complex organ that controls about every function of the body. It has three main sections:
1. Midbrain
2. Pons
3. Medulla oblongata or Medulla
The medulla oblongata is situated at the lowest portion of the brain. It connects to the pons on the upper side and the spinal cord on the posterior side. It is primarily responsible for controlling some autonomic functions, some of which are essential for human survival, such as ventilation ( pons work together with the medulla and produce rhythms for respiration) and cardiac function. Other functions involve controlling sneezing, hormonal balance, etc.
