The sciatic nerve is a sensory motor nerve with two divisions that innervate the muscles behind and below the knee. These divisions are the tibial and peroneal nerves. The sciatic nerve is a sensory nerve that originates from the 7th lumbar vertebrae and sacrum of a dogâs spinal cord.
1 Because prokaryotic DNA can interact with the cytoplasm, transcription and translation occur simultaneously. 2  Most prokaryotes contain only one copy of each gene (i.e., they are haploid). 3  Nonessential prokaryotic genes are commonly encoded on extrachromosomal plasmids.
All cells, whether they are prokaryotic or eukaryotic, have some common features. The common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.he common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.
