Protein Synthesis-how genes control the body
April 3, 2012


Please copy these notes into your notebook ----you will be tested on this material.....



Protein Synthesis: This is how genes control the body:



A. A codon is a sequence of three bases in DNA.



1. Each codon represents a specific amino acids.



2. Ribosomes assemble amino acids in the same order that they are listed in the DNA codons.



3. The amino acids will make a protein.



4. The order of the amino acids (determined by the DNA sequence) determines the shape of a protein.



5. The shape of a protein determines its function.




  • Therefore: The sequence of bases in DNA will determine the functions of all the proteins in the body.


  • The proteins build and run the body.



B. RNA carries the genetic code to ribosomes.
