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 descends under cover of the gluteus maximus and then along the middle of the posterior thigh. In terms of surface anatomy, the sciatic nerve leaves the pelvis a little more than a third of the way along a line from the posterior superior iliac spine to the ischial tuberosity (fig. 14-4).It then descends about halfway between the ischial tuberosity and the greater trochanter.he sciatic nerve descends under cover of the gluteus maximus and then along the middle of the posterior thigh.
