which is the difference between protein synthesis and breakdown
Protein biosynthesis - Wikipedia
To understand how proteins are made, we have to divide thedecoding process into two steps. DNA only stores the geneticinformation, it isn't involved in the process by which theinformation is used. The first step in protein biosynthesistherefore has to involve transcribing the information inthe DNA structure into a useful form. In a separate step, thisinformation can be translated into a sequence of aminoacids.

The messenger RNA now binds to a ribosome, where the messageis translated into a sequence of amino acids. The amino acidsthat are incorporated into the protein being synthesized arecarried by relatively small RNA molecules known as transferRNA, or tRNA. There are atleast 60 tRNAs, which differ slightly in their structures, ineach cell. At one end of each tRNA is a specific sequence ofthree nucleotides that can bind to the messenger RNA. At theother end is a specific amino acid. Thus, each three-nucleotidesegment of the messenger RNA molecule codes for the incorporationof a particular amino acid. The relationship between thetriplets, or codons, on the mRNA and the amino acids is shown inthe table below.
