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.
Making the world better, one answer at a time. The double helix of the DNA unwinds. Then, the enzyme helicase 'unzips' the DNA by breaking the hydrogen bonds. Then, the enzyme DNA Polymerase pairs each of the two strands with the correct nitrogenous bases.The top strand is called the 'leading strand' and the bottom strand is called the 'lagging strand.' Then the enzyme ligase glues together the different fragments of the lagging strand of DNA.Now we have two exact replications of DNA, each with 46 chromosomes called daughter cells.he top strand is called the 'leading strand' and the bottom strand is called the 'lagging strand.'
