The Claws of Axos standard. The story includes interior scenes inside the TARDIS for the first time in the Pertwee era of the show. The configuration of the TARDIS set-up is unique for this adventure. The TARDIS monitor appears to be a circular screen embedded in one of the 'roundels' in the console room wall, rather than the traditional rectangular screen (this feature is seen again once, a year later, on the unique set built for "The Time Monster"). The doors of the console room do not open directly into the exterior as in all other adventures; instead they open into a corridor that
Link domain Link domain A Link domain or Link module, also known as Xlink domain (X for extracellular), is a protein domain that binds to hyaluronic acid. It is important in blood cell migration and apoptosis. The link domain is found in some extracellular proteins in vertebrates such as the hyalectans. It appears to be involved in extracellular matrix assembly and stability, cell adhesion, and migration. The structure has been shown to consist of two alpha helices and two antiparallel beta sheets arranged around a large hydrophobic core similar to that of C-type lectin. This domain contains four conserved cysteines involved in
