6. DNA is a vast chemical information database that carries the complete set of instructions for making all of the proteins that guide cell functions. 7. Each different protein molecule consists of a long chain made from 20 different kinds of amino acids whose properties depend on the specific sequence of amino acids and the shape.

Fredrick Griffith – Genetic Material - Student will a poem, story or play about the Griffith experiment. Tell them that their creative work should demonstrate an understanding of the scientific process and the methods of Griffith experiment. Codons Have students a simple sentence in their notebooks. Each word must contain only three letters. For example, “the fat cat ate the big rat becomes Hef atc ata tet Then ask students to shift the letters. Point out that the three letter words model codons DNA Extraction from Corn - Report - Imagine you are the first researcher to extract DNA from corn. Write a report detailing your methods and possible applications of your discovery. To learn more about DNA extraction, visit BioLabs at . Francis Crick and James Watson- Have students do research in the library or on the internet to find out what Francis Crick or James Watson has worked on since discovering the structure of DNA. Students should organize their findings about the scientist’s work and write a short essay. (Practice 8/Literacy RST.11-12.9) Qualifications for Each Type of RNA An RNA molecule is looking for a job in a protein synthesis factory and it asks you to write its resume. This RNA molecule is not yet specialized and could, with some structural changes, function as mRNA, tRNA, or rRNA. The resume you create
