. Yes‚ comparably to TLC plate 2 and 3. The benzophenone is more neutral but as the same time its nonpolar‚ being that Silica gel in TLC 2 was polar and the solvent ethyl acetate-hexane is non-polar it moved relatively with the solvent. The stationary phase in TLC 3‚ alumina is non polar and the solvent ethyl acetate is polar so from the ideal that polar does not attract non-polar benzophenone stick stronger to alumina non-polar rather than moving up with polar solvent ethyl acetate as it did in

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein.
