In all species it is composed of two helical chains bound to each other by hydrogen bondsboth chains are coiled around the same axis and have the same pitch of 34 angstroms 34 nanometres. The structure of dna is dynamic along its length being capable of coiling into tight loops and other shapes. Welcome to the 35th anniversary season. Its primary function is packaging very long dna molecules into a more compact denser shape which prevents the strands from becoming tangled and plays important roles in reinforcing the dna during cell division preventing dna damage and regulating gene expression and dna replication.
