Here's a breakdown:

* DNA is the molecule that carries genetic instructions.

* Genome refers to the complete set of DNA within an organism. This includes all the genes and non-coding DNA sequences.

* The patterns within a genome are unique to each individual (except for identical twins).

It's important to distinguish between "genome" and "gene." A gene is a specific sequence of DNA that codes for a particular protein, while the genome encompasses all the DNA in an organism.
