Even the bark and the leaves are “planned” by DNA strands, and these strands can order the organism to gather materials. So DNA may be like the boss telling his employees to gather the buns and meat and fry a hamburger. He doesn’t contain the materials, but he gives orders to gather them. Is this on the right track?
Essentially yes. Also, remember that life is built out of proteins, which are basically made in the same way (by chaining approximately 20 amino acids together in various different ways). The DNA contains the recipe for which amino acids are combined together and thus which proteins are made, when and how much.
