The question requires the knowledge that Escherichia coli is a facultative, Gram negative, lactose fermenting bacteria. EMB (eosin methylene blue), or Mac (MacConkey) media is superior for isolating Escherichia coli because it is both selective and differential. Nutrient agar is neither selective nor differential. Selenium enriched media would not help identify this bacteria because Escherichia coli does not require this supplemented media to grow. Phenethyl alcohol can be used to select for anaerobic bacteria, which is of no utility in this situation.

The most commonly implicated bacteria in epiglottiits are H. influenzae type B, Streptococcus spp, and Staphylococcus aureus. _Campylobacter jejuni is a common cause of food poisoning.

Pili are short, hairlike structures on the surface of some bacteria. Conjugative pili can form a sort of tube between bacterial cells, allowing for the transfer of DNA from one bacteria to another.

Flagella are whip-like structures that allows bacteria to move within a fluid medium. Cilia are hair-like structures found primarily on the surface of mammalian cells, but are also found on bacterial cells, where they aid in attachment. A bacterial capsule is a polysaccharide layer outside the cell envelope that does not take part in bacterial conjugation, and may secrete "slime" which protects the bacteria from the surrounding environment.

This question requires that the student recognizes that the process illustrated is recombinant DNA (deoxyribonucleic acid) technique. It requires the understanding that the process of producing protein from RNA (ribonucleic acid) is termed translation. Replication is the process by which DNA is synthesized from DNA. Transcription proceeds translation and involves synthesizing RNA transcripts of specific sections of DNA. Transduction is one way bacteria exchange genetic information. Specifically, transduction involves the transfer of bacterial DNA via bacteriophage. Note that this is one way that a group of bacteria can become resistant to antibiotics without ever having been exposed to the antibiotic to which they are resistant.
