Here's a breakdown:
* DNA: DNA contains the instructions for building and maintaining an organism. It's like a blueprint that tells the cell what proteins to make and how to function.
* Genome: The entire set of DNA in an organism is called its genome.
* Chromosomes: In eukaryotic cells, DNA is organized into structures called chromosomes. Each chromosome contains a long, linear molecule of DNA.
* Genes: Segments of DNA that code for specific proteins or functional RNA molecules are called genes.
