in the first, the series is adenine followed by two thymine; in the second, adenine is followed by two thymine.
in the first, the series is cytosine - adenine - thymine; in the second, it is cytosine - adenine - adenine.
the first has thymine where the second has a guanine.
the first has a series of three nucleotide bases; the other has a series of four.

Protein synthesis actually begins in the nucleus when transcribes a single gene on the dna molecule is copied. the process of copying this gene is called this copy is known as and contains the protein building instructions. this copy is sent out into the cytoplasm to the part of the cell known as the the of the ribosome will join together to form a functional ribosome when they attach to the mrna. as the mrna moves through the ribosome, the message is read by transfer rna brings the correct back to the ribosome. the amino acids are placed in the correct order and are hitched together by
