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.
â¢ In eukaryotes, multiple replication sites are present in a single DNA molecule whereas, in prokaryotes, a single replication site is present in the circular DNA molecule. â¢ In prokaryotes, DNA replication involves three polymerase enzymes; namely, DNA polymerase I, DNA polymerase II, and DNA polymerase III.rokaryotic DNA and eukaryotic DNA vary widely; so do their replication processes. Prokaryotic DNA Replication. Unlike in eukaryotes, there is a single circular DNA exists in prokaryotes. The replication in the prokaryotic chromosome begins at the origin of replication.
