Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code

Similarities and differences are explained below
Explanation:
Differences:
somatic nervous system:
- It is part of the peripheral nervous system associated with the voluntary control of body movements through the skeletal muscles and mediation of involuntary reflex arcs.
- It has sensory and motor pathways.
- It controls muscles and movement.
- System responses are based on skeletal muscle contraction.
Autonomic nervous system:
- The autonomic nervous system is subdivided into the sympathetic nervous system and parasympathetic nervous system
- It possesses only motor pathways.
- It controls glands and internal organs.
- This system works automatically, without a person's conscious effort.
Similarities between the somatic nervous system and the autonomic nervous system:
Both have motor pathways
Both the system use nerve impulse
Both the system Weaken Myocytes
Both the system use glucose as an energy source for the muscles that they control
Both the system are controlled by the CNS
Both possess neurons
