Dna has this unique ability.

The pH level in humans is about 7.4 for most cellular functions
Proteins are the components of genes that perform most of the life functions and make up most of the cellular structure. Proteins are involved in almost every biological process in living organisms.
the brain controls most functions in the body.
Organelles, such as the nucleus, mitochondria, and chloroplasts, are tiny units that control most cell activities. These organelles carry out specific functions within the cell, such as DNA storage, energy production, and photosynthesis.
From the wikipedia article linked to below, Mitochondria generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in a range of other processes, such as signaling,cellular differentiation, cell death, as well as the control of the cell cycle and cell growth
The 'Big Three' are: i) Structural; ii) Functional; and iii) Regulatory. There most certainly are many others!
No, most protein and amino acid hormones do not directly interact with genes. Instead, they bind to specific receptors on the cell surface, triggering a cascade of signaling events within the cell that ultimately leads to a biological response. This allows for rapid and precise control of cellular functions without altering gene expression.
One of the most important functions of the cell membrane is to regulate the movement of dissolved substances (such as ions and nutrients) across the membrane. This selective permeability helps maintain internal cellular conditions and control the exchange of molecules with the external environment.
the nucleolus Nucleus
The nucleus functions most like the brain of a cell. It contains the cell's genetic material (DNA) and controls cellular activities by regulating gene expression. Just as the brain controls body functions, the nucleus controls the activities and functions of the cell.
They are logical functions, the most common one being the IF function.
