Regulation of enzyme activity: Cells can adjust activity of enzymes already present; fast and relies on chemical cues that increase or decrease enzymatic activity - Feedback inhibition: if an AA like trp accumulates in a cell, it shuts down the synthesis of more trp by inhibiting enzyme activity; allows a cell to adapt to short term fluctuations in supply of … WebThe negative charge of the DNA is due to phosphodiester bond that keeps the nucleotides and DNA within the nuclear membrane. Negatively charged molecules are insoluble in lipids therefore DNA cannot move across lipid made nuclear membrane. Phosphate groups can from linked bonds. The bonds formed from phosphates are ester bonds that are stable.
