If a gene is active, the RNA in the sample binds to the complementary gene fragment on the slide, and can be detected under ultraviolet light as a coloured dot.

It allows for reduction and fixation of the tibial tubercle fragment that is stable enough to allow immediate full active range of motion.

Lava balls grow when a small fragment of solidified lava rolls along the surface of an active flow and lava sticks or accretes to its surface.
