Genetically modified bacteria can be used to produce the enzyme phytase, which is added to animal feed to help livestock digest phosphorus.
Name the small, circular molecule of DNA found in bacteria that is commonly used as a vector to transport foreign genes.
Name the two specific enzymes required to insert the phytase gene into this bacterial vector.
To produce commercial quantities of phytase, the genetically modified bacteria are grown in an industrial fermenter.
Describe an investigation to find out how the incubation temperature of the growth medium affects the yield of phytase produced by these bacteria.
Your answer should include experimental details and be written in full sentences and paragraphs.
