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.
A human cell has genetic material contained in the cell nucleus (the nuclear genome) and in the mitochondria (the mitochondrial genome). In humans the nuclear genome is divided into 46 linear DNA molecules called chromosomes, including 22 homologous chromosome pairs and a pair of sex chromosomes. The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated with histone proteins. 2  All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. 3  Some eukaryotic organelles such as mitochondria also contain some DNA.
