A double helix structure has two sugar-phosphate backbones, one on each side of the helix. These backbones are made up of alternating sugar and phosphate molecules that support the DNA bases in the helix.
an example could be by the spine. Sliding joints occur between the bones in your backbones in your backbone. (These bones are called vertebrae.) In these joints the flat surfaces of two bones slide over each other and cause side-to-side and back-and-forth movement.

DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate.
There are 206 bones in the human skeleton. The bones are divided into two parts. 80 bones in the axial skeleton which are the bones in the center of the body. Like the ribs, the skull and the spine. And 126 bones in the appendicular skeleton. Which is made up of the limbs. Like arm, finger, leg, and foot bones.
