Definitions:

Chromosomes

Forty-six tiny strands of DNA, found in the nucleus of each cell of the body, which are the source of biological inheritance.

Genes

Functional units or sections of DNA that provide a blueprint or code to the cell for how to produce proteins and enzymes. Found on chromosomes, they come in matching pairs, one from each parent.

Zygotes

The initial cell formed when a sperm cell fertilizes an egg cell, representing the earliest stage of development in many organisms.

Allostasis

“Balance through adaptation.” In this model of stress processes, the central nervous system (CNS) controls multiple interacting regulatory processes so that the best balance for each specific challenge is found, rather than returning to a fixed set point.
