WebWhat are the functions of DNA polymerase? It helps in the formation of a DNA molecule by assembling nucleotides, the tiny building block of DNA. It helps in splitting the DNA molecule into two identical DNAs (DNA replication). It acts as a catalyst, which is important in DNA replication. Weba. The DNA double helix is composed of two strands of DNA; each strand is a polymer of DNA nucleotides. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases. The structure and orientation of the two strands are important to understanding DNA replication.
