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 biggest reasons for sciatic nerve pain development are herniated spinal discs and inflammation. For the majority of people, sciatic nerve pain is caused by a herniated disc in the back, which means a disc in the spine develops a slight crack or tear. A herniated disc sticks out into the spinal canal, which means it alters chemical messages that are sent via the nerves to the limbs. If a spinal disc protrudes out in a certain area, it can âpinchâ the sciatic nerve, which is one of the main channels of communication between the spine and legs. The sciatic nerve connects smaller branches of nerves that run through the spinal canal, from the pelvis down the legs and into the ankles and feet.
