Answer by Stevekim012. Confidence votes 16.0K. Nucleotides. A single nucleotide contains a phosphate group, deoxyribose or ribose (depending on the nucleic acid) and a nitrogen base, which can be adenine, guanine, cytosine, thymine, and uracil. These monomers combine to form polymers known as DNA or RNA.nswer by Stevekim012. Confidence votes 16.0K. Nucleotides.

Save. The sciatic nerve is the largest nerve in the body and runs from the lower portion of the spine, through the buttocks and down into the thigh and lower leg. It is responsible for feeling and movement in the major muscles of the hamstring, lower leg, and foot.
The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back. It goes down through the buttock, then its branches extend down the back of the leg to the ankle and foot. What causes sciatica? The most common cause of sciatica is a bulging or ruptured disc (herniated disc) in the spine pressing against the nerve roots that lead to the sciatic nerve.
