Anabolism involves all the series of chemical reactions that brings about building of larger macromolecules from smaller ones. An example is protein synthesis which involves the build up of smaller molecules eggs amino acids to form larger macromolecules: proteins. In DNA replication/synthesis of DNA, it involves breaking of the bonds between the original two strands and then formation of bonds between the old and newly synthesized strands. Synthesis of two new strands of DNA. Thus it is a build up process, a process of anabolism.
