(a)
Interpretation:
The IUPAC name has to be given for the substituted benzene derivative.
Concept Introduction:
When hydrogen atoms are replaced by one or more groups in benzene is known as substitution reaction and the compounds produced is benzene derivatives.
Benzene derivative with one substituent:
IUPAC system of naming monosubstituted benzene derivatives uses the name of substituent as prefix to the name benzene. If the group that is present in benzene cannot be named easily means, then the benzene ring is often treated as group attached to this substituent. The benzene ring is known as phenyl in this approach.
Benzene derivative with two substituents:
When benzene ring contains two substituents it is known as disubstituted benzene derivative. Three isomers are possible for the disubstituted benzene derivative. The prefix used in IUPAC name are,
Ortho- means disubstitution in 1,2
Meta- means disubstitution in 1,3
Para- means disubstitution in 1,4
When both the substituents present on the benzene ring imparts a special name, where all the substituents are cited in alphabetical order before the ending –benzene. The carbon that bears the group with alphabetical priority is given number 1.
Benzene derivatives with three or more substituents:
More than two groups are present in the benzene ring means, their positions are numbered. The numbering is always done in a way that the carbon atom bearing substituent gets the lowest numbering possible. If there is a choice of numbering system, then the group that comes alphabetically first is given the lowest number.

- Overview of Transformation Protocol -Prepare competent bacteria for transformation: Treat starter E. coli bacteria with CaCl2and Competent Cell Solution (CCS). Store on ice until transformation procedure. Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed. -Transformation procedure: Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA. Add CaCl2 to both tubes. Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube. Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes. Add recovery broth to both tubes.

You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have shipped your samples off for sequencing and are now waiting for the results. Out of curiosity (and maybe boredom...) you decide to test your culture for the Catalase and Oxidase enzymes. Upon testing your sample for catalase, you don't see any bubbles; however, you do see a color change to purple during the Oxidase test. What results can you conclude from this?

You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have already cultured it and gone through the plate isolation procedure. Before you ship your samples off for sequencing, you want to do one final check of the A260 ratios. You get back the following ratios: A260/280 ratio is 1.89; A260/230 is 2.01. These ratios are close enough to the accepted "pure" values so they could be considered "pure" and mostly (if not completely) free of contaminants from the PCR process.

The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. After receiving your sequence back from the sequencing lab, you feel that you have, in fact, discovered and isolated a new species. You ask a fellow labmate about how you should proceed, and he tells you the following is the proper way to introduce a new species for recognition: Cultures have to be sent to international culture collections. Then a paper must be published describing the new organism and providing a genus and species name. You recall learning about this in your Microbiology course in college.
