These attachments cause an abnormal stretching of the spinal cord. The course of the disorder is progressive. In children, symptoms may include lesions, hairy patches, dimples, or fatty tumors on the lower back; foot and spinal deformities; weakness in the legs; low back pain; scoliosis; and incontinence.hese attachments cause an abnormal stretching of the spinal cord.

This does not happen in prokaryotic cells.     Eukaryotic cells have more than one chromosome.     A further difference: prokaryotic chromosomes consist only of a naked DNA molecule, but eukaryotic chromosomes also contain many molecules of proteins (mostly histones). The DNA is wound around these proteins.
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles.Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. Cell division is part of the life cycle of virtually all cells. 2  Cell division is the process in which one cell divides to form two new cells. 3  Most prokaryotic cells divide by the process of binary fission. 4  In eukaryotes, cell division occurs in two major steps: mitosis and cytokinesis.
