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.
Promoters of prokaryotic organisms, e.g., such as bacteria, have similar elements as the eukaryotic promoters although there are a few basic differences. 1  Prokaryotic promoters contain at least three conserved features defining the region where the RNA polymerase binds: 2  the start point, defined as +1; the TATA box is located at -10 position to the start point; in contrast to the -35 bp in eukaryotic promoters; and. the TTGACA sequence, also called the -35 sequence, located around 35 bp upstream of the start point.
