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.
(Recall that prokaryotic cells do not possess a nucleus.) Prokaryotic chromosomes are less condensed than their eukaryotic counterparts and don't have easily identified features when viewed under a light microscope. Figure 2: A the appearance of DNA during interphase versus mitosis.Recall that prokaryotic cells do not possess a nucleus.)
