Here's a breakdown:
* DNA is a molecule that carries the genetic instructions used in the development, functioning, growth, and reproduction of all known living organisms and many viruses.
* It's organized into structures called chromosomes. Humans have 23 pairs of chromosomes (46 total), with one set inherited from each parent.
* Each chromosome contains thousands of genes, which are segments of DNA that code for specific traits. These traits can range from eye color to susceptibility to certain diseases.
* The sequence of nucleotides (building blocks of DNA) within a gene determines the specific protein that gene will produce. Proteins perform a wide variety of functions in the body, making DNA the blueprint for all living organisms.
Essentially, your DNA is like a recipe book that contains all the instructions needed to build and maintain you.
