The packets of information in each cell's nucleus are called chromosomes.

Here's a breakdown:

* Chromosomes are made up of DNA (deoxyribonucleic acid), which contains the genetic instructions for building and maintaining an organism.

* Genes are segments of DNA that code for specific traits.

* Chromosomes are organized structures of DNA and proteins that are found in the nucleus of every cell.
