Question

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.

Answer 1

The amino acids that make up the DNA molecule contain the information needed to make cellular proteins.
