Which viruses have single-stranded RNA that acts as a template for DNA synthesis? The water will mostly move from side "B" to side "A" because the water concentration is higher on side "B." These special proteins tell the white blood cells those bacterial cells do not belong to that particular human and to phagocytize (eat) them. transcriptional regulators of HLA class II loci. d. The water will not move at all because the water concentrations are isotonic.
