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.
Most prokaryotes have a single loop of DNA for their genome while most eukaryotes have multiple pieces of linear DNA (the packaging of the DNA is also different between eukaryotes and prokaryotes). There are also significant differences between eukaryotic and prokaryotic ribosomes.ost prokaryotes have a single loop of DNA for their genome while most eukaryotes have multiple pieces of linear DNA (the packaging of the DNA is also different between eukaryotes and prokaryotes).
