Members can differ in celular location, 006 * sequence features, SNPs, mutations and bound partners.

A gene can possibly span 010 * multiple DNA molecules, sometimes even across chromosomes due to regulatory 011 * regions. Similarly a gene is not necessarily made up of deoxyribonucleic acid 012 * and can be present in multiple copies ( which are different DNA molecules). 013 */ 014 015public interface DnaReference extends NucleicAcidReference 016{ 017 018}
