I think it's the pituitary glands.

Cells.
Genes control the expression of (genetic) traits and are responsible for determining the inherited characters, they are therefore called units of inheritance.
Weight is measured in units called newtons , while mass is measured in units called grams and kilograms.
In terms of colonies or colony forming units (CFU).
Yes, living things are made up of units called cells, which are the basic structural and functional units of life. Cells contain the biological machinery necessary to carry out the processes essential for life, such as growth, metabolism, and reproduction. Each cell is capable of performing specific functions to contribute to the overall well-being of the organism.
Repeating units of actin and myosin filaments are called sarcomeres. These are designed to control the contraction of muscles in the human body.

The Analytical machine had five units- input, output, store, mill, and control. Store was used for storing numbers and Mill was used to do the calculations by rotation of gears and wheels. Control unit did the job of supervision of all other units. Note that these five units are similar to the functional units of a modern digital computer.No wonder he was called the "Father of Computers"! He was Charles Babbage.
Those are called derived units.
Cells.
Genes are the fundamental units of inheritance. Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring.
Probably the Control Unit, as it tells all the other units what to do and when to do it.
Genes control the expression of (genetic) traits and are responsible for determining the inherited characters, they are therefore called units of inheritance.
Any single celled organism carries out the functions of life, but, if considered living, a virus is much smaller than a cell. However, viruses are only DNA and can do little except control a cell with their DNA. They do not eat, or control their own movement, nor can they reproduce without a host.
They are genes.
