An oxygen sensor failure can lead to incorrect readings of exhaust gasses. The faulty sensor can cause a too rich or too lean condition. Too rich and the catalyst can meltdown. Too lean and the converter is unable to convert the hydrocarbons into safe elements and may not pass a state inspection. Road Damage or Broken Hangers.
Within the centrosome, the centrioles are positioned so that they are at right angles to each other, as illustrated in Figure 1. Each centriole is made of nine bundles of microtubules (three per bundle) arranged in a ring. Centrioles play a notable role in cell division. During interphase of an animal cell, the centrioles and other components of the centrosome are duplicated, though scientists are not yet sure how this duplication takes place.
Role of RNA in Protein Synthesis. In all living cells, the process of translating genetic information from DNA into the proteins that do most of the work in a cell is carried out by molecular machines made of a combination of RNA and protein. Surprisingly, it is the RNA, and not the protein, that does the critical work in this protein-making machine, which is called the ribosome.
