38. Summary
The first step is transcription. The first step in transcription
is the unwinding of the DNA molecule so that some DNA
that codes for the needed protein can be transcribed. After
the DNA molecule unwinds, the enzyme, RNA polymerase
lines up nucleotides to create a strand of mRNA. After
transcription, the new RNA strand is released and the two
unzipped DNA strands bind together again. Since after
this occurs the DNA strand is back to normal this step can
repeat.

39. Summary
The next step is Translation. In this, mRNA is sent to the
cytoplasm, where it binds to the RNA. Once the mRNA is
in place, tRNA molecules bind to the ribosome defined by
the mRNA code. At its tail end, tRNA has a “stem” that
attaches to a specific amino acid. At its head, it has three
nucleotides that make up an anticodon. Translation begins
with the binding of the mRNA chain to the ribosome. The
tRNA molecule forms a base pair with the mRNA. A
peptide bond is formed between the amino acid attached
to the tRNA.
