How do nucleotides and hydrogen bonds affect the structure of DNA?

Maybe something like nucleotides make up DNA and hydrogen bonds hold the nitrogenous bases together?

Can you help me explain?

that's true, also nucleotides affect DNA in deciding what it codes for; therefore it is affecting structure in general.
DNA is a group of nucleotides that are linked together. The hydrogen bonds are responsible in making the double helix structure stable. The two strands of DNA are linked and stays in a stable shape because of the hydrogen bonds located between adenosine and thymine base pairs. Three hydrogen bonds are between cytosine and guanine.
