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.
Animals, plants, fungi, and protists are all eukaryotes. Eukaryotic cells are more complex than prokaryotic cells and are found in a great many different forms. The nucleus contains most of the genetic material (DNA) of the cell. Additional DNA is in the mitochondria and (if present) chloroplasts.nimals, plants, fungi, and protists are all eukaryotes.
