In Experiment 1, why is exposure to UV radiation an effective method of controlling bacterial growth? A. It damages DNA, inhibiting transcription and replication. B. It causes the cell membrane to rupture. C. It creates ions that damage biomolecules. D. It raises the temperature, killing temperature sensitive bacteria.

2) A blotting method known as Western blotting can be used to detect proteins that are translated from a particular mRNA This techniques first separates proteins by size using electrophoresis then detects specific proteins through staining (antibody directed). Key is that you can visualize only the protein of interest on the gel. Suppose a researcher was interested in the effects of mutations on the expression of a gene that encodes protein X This protein is expressed in the skin and...

Part 1 In this section, we relook at the main method by examining passing array as parameters. Often we include options/flags when running programs. On command line, for example, we may do “java MyProgram -a -v". Depending on options, the program may do things differently. For example, "a" may do all things while "-v" display messages verbosely. You can provide options in Eclipse instead of command line: "Run ... Run Configurations ... Arguments". Create a Java class (Main.java)....
