Use this information to answer the question(s) below. suppose an experimenter becomes proficient with a technique that allows her to move dna sequences within a prokaryotic genome. if she moves the promoter for the lac operon to the region between the beta galactosidase (lacz) gene and the permease (lacy) gene, which of the following would be likely? use this information to answer the question(s) below. suppose an experimenter becomes proficient with a technique that allows her to move dna sequences within a prokaryotic genome. if she moves the promoter for the lac operon to the region between the beta galactosidase (lacz) gene and the permease (lacy) gene, which of the following would be likely? the three structural genes will be expressed normally. the cell will continue to metabolize but more slowly. beta galactosidase will not be produced. the operon will still transcribe the lacz and lacy genes, but the mrna will not be translated. rna polymerase will no longer transcribe permease.

Beta galactosidase will not be produced

Explanation:

Normally in lac operon, promotor is located before genes and it is necessary for the initiation of transcription.

Lactose operon or lac operon  (includes lacZ  lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent. The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.

When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.

CAP detects glucose (via cAMP) and activates transcription when glucose levels are low/

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
