46. Summary
Protein Synthesis is fairly simple. The first step is RNA
polymerase unwinds a DNA strand and synthesizes a
mRNA strand. This is because the DNA strand is too big
to fit through the nuclear pores and the DNA must stay
in the nucleus. Next, the mRNA strand leaves the
nucleus through the nuclear pores into the cytoplasm
and comes in contact with a ribosome. The ribosome
reads the mRNA strand and coverts it into an amino acid
sequence. Last, once the amino acids are connected by
peptide bonds, the amino acids forms into a three
dimensional figure (tertiary structure). The protein does
not have a function until it is in a three dimensional
figure.
