Question

select the part of the dna molecule that codes for our traits.

Explanation:

DNA is composed of nucleotides. Each nucleotide has a phosphate group (circle), a deoxyribose sugar (pentagon), and a nitrogenous base (arrow - shaped). The sequence of nitrogenous bases (adenine, thymine, cytosine, guanine) in DNA codes for our traits. Different sequences of these bases determine the genetic information that is translated into proteins, which in turn influence our traits.

Answer:

The nitrogenous base (the arrow - shaped part in the diagram) is the part of the DNA molecule that codes for our traits.
