sequences mutations assess the levels of specific proteins or study the processes involved in protein synthesis These analyses have a wide range of applications from basic research to clinical diagnostics The Mechanics of DNA and Protein Synthesis Before diving into the tests a brief understanding of the underlying biological processes is essential DNA or deoxyribonucleic acid carries the genetic instructions for building and maintaining an organism Through a process called transcription DNAs information is copied into messenger RNA mRNA This mRNA then travels to the ribosomes the protein manufacturing machinery of the cell Translation then occurs where the mRNA sequence dictates the assembly of amino acids into a specific protein Key Components in Protein Synthesis DNA The master blueprint mRNA The intermediary carrying the genetic code Ribosomes The protein synthesis machinery tRNA The delivery trucks for amino acids Amino acids The building blocks of proteins Types of
