Genomic mammalian dna cannot be expressed directly using bacterial expression vectors because mammalian genomic dna contains introns. true or false

The biological membranes like the cell membrane or the membrane enclosing the organelles are all semi-permeable. The semi-permeability is the property of membranes that gives them the ability to selectively allow the movement of particles/ solute/ solvent across it. The semi-permeability allows the cell to maintain a concentration gradient across its membrane that further drives various cellular processes within the cell.
