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.
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication. Prokaryotic replication does not require a primer. DNA polymerases of prokaryotes can add nucleotides to both 3 and 5 ends of DNA strands, while those of eukaryotes function only... show more Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication. Prokaryotic replication does not require a primer. DNA polymerases of prokaryotes can add nucleotides to both 3 and 5 ends of DNA strands, while those of eukaryotes function only in the 5â3 direction.
