DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). <span>DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.</span>
The circulatory and skeletal systems work together in the following way: skeletal system produces cells in the bone marrow while the circulatory system transports cells where they need to go (option A).
<h3>What is skeletal and circulatory system?</h3>
Skeletal system is the system that works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
Circulatory system, on the other hand, are parts of an animal body comprising the heart, veins, capillaries and arteries. It circulates blood and lymph through the body.
According to the above description of both systems, the skeletal system produces blood cells in the bone marrow while the circulatory system transports these cells.
