Answer:
The rate of activity of an enzyme might change as pH changes
Explanation:
Enzymes are organic catalysts that controls the rate of a specific chemical reaction.
These materials combines substrates in order to lower the activation energy which might serves as a barrier to chemical action.
- Enzymes have specific reactions which they control.
- Temperature and PH conditions control the rate at which enzymes work.
- They are not all produced from the building block of carbohydrates.
Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.
