The Question: What does it mean to be an extremophile? Describe one extremophile condition and explain how it would relate to the environment that a prokaryote is growing within. How might it alter their growth cycle/curve?
The Person's Response: Halobacterium are bacteria that are either rods are cocci and require a relatively large amount of salt to thrive. A lot of the proteins that they contain will not function properly or at all in a low sodium environment. Halobacterium are found in the Dead Sea, the Great Salt Lake, and other places that are favorable to their physiology. Their preferred temperatures are around 37 degrees Celsius, which is generally the optimum temperature for most bacteria. So they aren't thermophiles, but do thrive in a different extreme condition.

Pls me i need this ! each cell has genes activated depending on it's job and what kind of cell it is. it is the presence of that causes the repressor protein to fall off and unblock the gene on the lac operon. if a gene is turned on then it is being an additional circular chromosome found in some bacteria that is used in genetic engineering.

Transposon can cause mutations in genes at or near the site of transposon insertion. it is possible for these elements to transpose away from their original site, causing a reversion of the mutant phenotype. in some cases, however, even more severe phenotypes appear when these elements excise from this site, due to events at or near the mutant allele. what might be happening to the transposon or the nearby gene to create more severe mutations?
