Which of the following situations is not a segregation of duties violation?

When a toll like receptor (TLR) gene was first discovered in fruit fly (Drosophilamelanogaster) in 1996, it was unclear whether its homologues exist in mammals. Please design experiments (in other words, write the techniques you would use) to answer the following questions (4 points for undergrads, 2 points for graduate students): A) Do mice have the TLR genes?B) Are the TLR homologue genes transcribed at different levels in different tissues? (graduate students describe at least two different approaches in detail)C) Are TLR proteins expressed at different levels after viral infection?D) Are the TLR proteins expressed on the plasma membranes? (graduate studentsdescribe two different approaches in detail)

In this process, two pyruvic acid molecules are produced from one glucose molecule.

If you want to make a fusion protein linking your protein of interest to a protein tag (e.g. GFP), you must remove _____ between the DNA sequences that code for the two proteins.

You have 2 strains of bacteria. One is resistant to ampicillin and the other is resistant to spectinomycin. You mix together the 2 live strains, and to your knowledge, no phages are present in the mixture. After several hours, you plate the mixture on agar plates containing both ampicillin and spectinomycin and get several colonies of bacteria resistant to both antibiotics.Based on the information given, what is the most likely mechanism that has produced the strain now carrying both genetic markers?

The genomic RNAs of the negative RNA viruses can be infectious once they get into permissive host cells.

Influenza virus is a positive strand RNA virus and Coronavirus is a negative strand RNA virus.

What component is NOT needed for a PCR reaction?

The stop codon UAG signals the DNA polymerase to stop replicating the chromosome.
