When transforming bacterial cells, a researcher is interested in generating bacteria that exogenously express the gene that enco

des GFP (green fluorescent protein). After transformation, she finds that no bacteria colonies grew on her selective media. Which of the following best explains the results of her transformation protocol?
a. The concentration of the antibiotics in the selection media was too low, therefore no bacteria grew.
b. Her bacterial cells were not competent so they took up excessive amounts of the GFP-containing plasmid.
d. She forgot the heat-shock step, so the DNA was not forced into bacterial cells.
d. The plasmid that she used contained a sequence that encoded antibacterial resistance.

Most enzymes fall into which group?
Rus_ich [418]
I am pretty much sure that C. Lyases is the answer.

Let me give some information about this.

Lyases are the main groups which show peculiarity in having more than several categorised groups having more enzymes than the other four.

Hydrolase does not fit this bill instead they contain less categorised groups.

Other two groups are not even having that much groups.

Hope helps ...

Natasha2012 [34]

Answer:

D) Beta galactosidase will not be produced.

Explanation:

Promoter is necessary to start the transcription of the structural gene. The position of promoter is important because the gene which is downstream to promoter will be transcribed and the gene upstream to the promoter will not be transcribed.

Lac operon has three structural gene lacZ, lacY, and lacA. Lac Z codes for β galactosidase, lac Z codes for permease and Lac A codes for transacetylase. So if promoter for the lac operon moves between the beta-galactosidase (lacz) gene and the permease (lacy) gene, then the beta-galactosidase gene will not be produced because it is places upstreamed to the promoter.
