The DNA double helix wraps around a protein scaffold, which condenses, and joins with another condensed protein scaffold, which are more commonly known as the sister chromatids. These chromatids are also called a DNA chromosome. However, one strand of DNA has all the genes on it (AKA the nitrogenous bases A, T, C, and G; A matches with T, C matches with G - base pairing rules. These bases are kept together by weak hydrogen bonds.)
You're welcome, kid.
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
