Hope this helps! :)
When there is a base substitution in DNA causes the mRNA to be transcribed differently in this example GGA would be transcribed to CCU and TGA would be transcribed to UCU.
Osmosis is the process by which solvent molecules move through a semi permeable membrane from a region of low concentration to the region of high concentration. The movement of the solvent depend on the solute concentration at each side of the plasma membrane. In a situation, where the solute concentration on both side of the membrane is the same, then there will be no net movement of solvent across the membrane.
Body cells have specific ideal concentration levels for each ions in the cell, osmosis help to maintain this concentration by means of osmoregulation. Osmoregulation is the process by which constant osmotic pressure in the fluid content of cells is maintained by the control of salt and water concentration.
