Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
Regarding cellular phones, the <u>electronic serial number (ESN)</u> is a code used to reset a forgotten pin.
- An electronic serial number (ESN) is the distinctive identification number that the manufacturer embeds or inscribes on the wireless phone's microchip.
- The ESN is automatically sent to the base station each time a call is placed so that the mobile switching office of the wireless carrier can verify the legitimacy of the call. In the field, the ESN cannot be easily changed.
- The mobile identification number (MIN), which is used by wireless carriers to identify phones on their network, is different from the ESN.
- To aid in preventing fraud, MINs and ESNs can be electronically checked.
