It might also be an important cause of hip osteoarthritis (OA). Therefore in this study we evaluated the frequency of cam-type FAI in axial spondyloarthritis (axSpA) patients as a potential alternative cause of hip or trochanteric pain.
Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitosis. In sexual reproduction, a male gamete fuses with a female gamete to produce a new cell. This is called fertilisation. Gametes are produced by a type of cell division called meiosis.
The DNA in eukaryotes, which are wrapped around histone proteins, are called nucleosomes. The DNA in eukaryotes is linear, and nucleosomes fold through a series of successively higher order structures to eventually form a chromosome. The DNA in prokaryotes, which form a mass, are called a nucleoid. Most DNA in prokaryotes is circular, and they are supercoiled to keep them gathered together.
