Answer:
DNA
proteins
genes
chromatin
chromosomes
chromosome
Explanation:
The “code” for physical traits is found in a molecule called DNA. Segments of this molecule that code for specific proteins are called genes. In order to conserve space and protect the molecule, DNA wraps around proteins to form chromatin. When a cell is about to divide, DNA wraps up even tighter into chromosomes. Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.
