2 Each DNA strand is composed of nucleotides—units made up of a sugar , a phosphate group, and a nitrogenous base Each strand of DNA is a Summary DNA is a molecule found in most cells holding each person's unique genetic code It is responsible for coding proteins, which are essential to the

This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands Replication relies on complementary base pairing, The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose , a phosphate group, and a nitrogenous base (Figure
