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.

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

what is the question here. i think you messed up.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
