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.
DNA is the heredity material of the cell. Some cells (bacterial cells) have one large circular DNA strand. In other organisms like us (aka eukaryotic cells) the dna for the cell is in several linear strands instead of one large circular piece of DNA. Each one of these strands of DNA is called a chromosome. The DNA of each chromosome is really tightly wound up around proteins called histones. Finally, a gene is a small segment of DNA, found in a small section of the chromosome (These can often be seen as dark bands in pictures of chromosomes). It is here, at the gene, that the DNA uncoils and opens up momentarily in order to have the gene 'read' and eventually copied into a protein (aka polypeptide).
