Full assembly structure

In a full implementation, the nesting of levels of assemblies is restricted such that (including world and component) the maximum nesting level is eight. A possible but not necessary interpretation corresponds to the following hierarchy  

Assemblies in the world scope are to be interpreted as representations different product families 

Assemblies in the next assembly level scope are to be interpreted as representations of different assemblies (in a mechanical engineering sense) that constitute an operational group within the whole product.

Adhesive bonding has many advantages, including more uniform stress distributions in comparison to the use of mechanical fasteners such as bolts, rivets, etc. Adhesives provide full contact with mating surfaces, thus forming a barrier to fluids and gasses which may cause degradation in the assembled structure. Adhesives can also function as electrical and/or thermal insulators or conductors in joints.

Hampel and Burke observed that protection of hammerhead backbone sites in Mg + solutions required assembly of the full ribozyme-substrate complex. In other words, testing of ribozyme or substrate separately in the hydroxyl footprinting assay showed essentially complete hydrolysis of all nucleotides (Figure 2B of reference 56). In contrast, the fully assembled ribozyme-substrate complex showed protection of nucleotides structurally near the densely packed three-helix junction of hammerhead constructs HH16, HHal, and RNA 6. Two of the ribozyme group of protected nucleotides (Gs, Ae) are part of the conserved uridine U-turn seen in all known hammerhead constructs. (See Figures 6.10,6.11, and 6.12.) The footprinting results are collected in Table 6.5.
