Transcript
Cracking the Code A GENE is a section of a DNA molecule that contains the information to code for one complete protein PROTEINS are made up of a chain of amino acids Proteins determine many of the traits in an organism DNA is made up of a chain of nitrogen bases: A, T, C, G The ORDER of nitrogen bases along a gene forms a genetic code that specifies which amino acids are put together to form the protein Messenger RNA carries the genetic code from the DNA in the nucleus to the cytoplasm Messenger RNA attaches to a ribosome, which “reads” the code 3 bases at a time (codon) Transfer RNA’s, attached to amino acids, pair with the 3-letter codes of messenger RNA The amino acids link in a chain, creating a protein molecule You will transcribe DNA into RNA, then translate RNA into “protein” Work in groups of 3: 1 messenger RNA 1 ribosome 1 transfer RNA Each member has specific instructions Raise your hand when you’ve cracked the code!
