As a result, leather is made up of interlaced bundles of coUagen fibers (Fig. 1). A schematic model of coUagen bundles in leather is shown in Figure 2 (4). A coUagen bundle (about 80 )Tm in diameter) is made up of coUagen fibers (1—4 pm), composed of microfibrils (0.08—0.1 pm). Furthermore, a microfibril consists of many protofibrils (about 1.5 nm), which consist of several bundles of polypeptide chains. [Pg.88]

Figure 9.2 Schematic model for transcriptional activation. The TATA box-binding protein, which bends the DNA upon binding to the TATA box, binds to RNA polymerase and a number of associated proteins to form the preinitiation complex. This complex interacts with different specific transcription factors that bind to promoter proximal elements and enhancer elements.

Develop a schematic model with fiber springs and matrix springs in which the actual surrounding of the fiber with matrix material is taken into account, i.e., for a cross section such as that with the dimension lamina thickness in Figure 3-2, except make the fiber cross section square instead of round. [Pg.136]

The schematic model is depicted in Fig. 8. As the bias voltage increases, the number of the molecular orbitals available for conduction also increases (Fig. 8) and it results in the step-wise increase in the current. It was also found that the conductance peak plotted vs. the bias voltage decreases and broadens with increasing temperature to ca. 1 K. This fact supports the idea that transport of carriers from one electrode to another can take place through one molecular orbital delocalising over whole length of the CNT, or at least the distance between two electrodes (140 nm). In other words, individual CNTs work as coherent quantum wires. [Pg.170]

The methods presented above give upper estimates of blast parameters. Since the measured blast parameters of actual pressure-vessel bursts vary widely, even under well-controlled conditions, and since these methods are based on a highly schematized model, the blast parameters of actual bursts may be much lower.

The schematic model of the film deposited by the technique is shown in Figure 45. A single-stranded DNA layer is sandwiched between two aliphatic amine monolayers. Thus, the technique can be useful for our objectives, for it allows depisition of single-stranded DNA on practically any substrate and does not demand a large quantity of DNA, since only one monolayer will be deposited. Nevertheless, there is a question of whether DNA in such a structure will hybridize. In fact, the film contains a single-stfanded DNA monolayer between two amine monolayers, and it is questionable whether the upper amine monolayer will prevent hybridization with complementary DNA stfands.

Figure 39-15. The leucine zipper motif. A shows a helical wheel analysis of a carboxyl terminal portion of the DNA binding protein C/EBP. The amino acid sequence is displayed end-to-end down the axis of a schematic a-helix. The helical wheel consists of seven spokes that correspond to the seven amino acids that comprise every two turns of the a-helix. Note that leucine residues (L) occur at every seventh position. Other proteins with "leucine zippers" have a similar helical wheel pattern. B is a schematic model of the DNA binding domain of C/EBP. Two identical C/EBP polypeptide chains are held in dimer formation by the leucine zipper domain of each polypeptide (denoted by the rectangles and attached ovals). This association is apparently required to hold the DNA binding domains of each polypeptide (the shaded rectangles) in the proper conformation for DNA binding. (Courtesy ofS McKnight)...
