what holds the sides of the DNA ladder together
The sternum is a long, flat bone located at the center of the chest that connects to the ribs on both sides. It serves as an important attachment point for various muscles and ligaments, providing structural support to the chest cavity. The sternum is also commonly referred to as the breastbone.
DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G). A and T are connected by two hydrogen bonds. G and C are connected by three hydrogen bonds.
The retina has two types of cells used in vision, rodsand cones. Cones, concentrated in the center of the retina, serve both color vision and the highest visual acuity. Rods, concentrated away from the center -- at the "sides," as you phrased it -- are responsible for night vision, for our most sensitive motion detection, and for our peripheral vision (vision of objects to the side, away from the center). Paradoxically, your night-vision is enhanced it you do not look directly at objects that are in relative darkness. If you drive at night on poorly lighted roads, for example, you can enhance your night-vision of passing cars and of the sides of the road by looking straight ahead: the rods will detect motion, objects on the periphery (the sides), and objects in relative darkness. If you were to look directly at objects in darkness, you would be stimulating the cones, in the center of the retina, and your night-vision would be less effective.
The sides of the DNA double helix are formed by alternating sugar (deoxyribose) and phosphate molecules, which make up the backbone of the structure. The sugar-phosphate backbone provides stability and support for the nitrogenous bases in the center of the helix.
A chromosome holds genetic information for the organism.
each side of the chromosome is called a chromatid they are bonded together by the centromere

The chromosomes have to split and go to opposite sides of the cell.
A glasscontainer with a glass lid on it.
Yes
you add all of the sides together for example if the sides were 4, 3, 4,3 you would have the answer of 14loopydingoAdd all the sides together
