How does structure of dna relate to the process of replication and protein synthesis?

Hello Sophia,
The structure of DNA relates to the process of replication and protein synthesis actually in many ways. DNA is a nucleus acid, one of the 4 major macromolecules (polymers). It provides the instructions for making proteins. When DNA replicates, one strand is used as a template for DNA polymerase to joint corresponding nitrogenous bases. Small, individual sections of the DNA are called genes, which code for a specific protein. STRUCTURE ALWAYS DETERMINES FUNCTION! Thus, DNA tells the cells which amino acids (building blocks of proteins) and in what order for the ribosomes (found in the cytoplasm) to synthesize. These proteins then determine our traits and characteristics. It may be more than you need, but hopefully it helps somewhat. Great question, though! Biology is so interesting, when you think about it! It makes our world and our selves.
