This is possible because of the length of the protein. It is always possible to add more amino acids and synthesize new protein and every new addition increases the number of possibilities drastically.
Answer: It is Hypertonic solution.
Explanation:
Hypertonic solution is a solution in which the the solutes Concentration outside the cells is greater than solute concentration inside the cell. When a cell is in Hypertonic solution, water will move out of the cell and it will shrivel. The cell will shrinks or cremated and may eventually die.
B) a smokestack for an electric power plant
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.
