How does the simple primary and secondary structure of dna hold the information needed to code for the many features of multicellular organisms?
the base sequence of dna carries all the information needed to code for proteins.
the hydrogen bonding among backbone constituents carries coded information.
the amino acids that make up the dna molecule contain the information needed to make cellular proteins.
the width of the double helix changes at each gene due to differences in hydrogen bonds.

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
