Yes, the backbones of the DNA molecule are identical in all living things. The backbone consists of alternating sugar (deoxyribose) and phosphate groups, which are the same across all organisms. However, the sequences of the nitrogenous bases (adenine, thymine, cytosine, and guanine) that attach to this backbone vary, providing the unique genetic information for each species.
