Example text

Replacement or point mutations are of three types: (1) nonsense, in which a transcription termination codon is produced, (2) synonymous, where a different code is produced but, because the code is degenerate, there is no amino acid substitution, and (3) missense, where a changed code results in an amino acid replacement. Mutations can also involve gross duplications, deletions, or translocations of such a degree as to be obvious under the light microscope (Figure 2-13). T C G i A i C G i C | A i i i !

Specimens contaminated by plasmid or other microorganisms can cause considerable problems in DNA profile interpretation. This separation includes glassware, pipettes, gel apparatus, and other possible sources of DNA transfer. Although duplication of minor equipment will be necessary, the use of disposable labware is one key to success of this operation. Bacterial culture facilities required to amplify and characterize vectors include an incubator shaker, refrigerator, -20°C freezer, spectrophotometer, microfuge, clinical centrifuge, electrophoresis apparatus, and an autoclave.

Radioisotopes should be stored only in designated areas under controlled conditions; this usually means in the ordering laboratory. Because facilities are not usually available for monitoring radioactive leaks, the receiving department should not open incoming packages. This process is the responsibility of the user. Radioactive materials cannot be accepted during off-duty hours unless special arrangements are in place. The user is responsible for tracing any materials not received when expected.
