DNA-->mRNA--> [ribosomes-->amino acids] -->PROTEIN! -->TRAIT!

Today's Lesson: We learned about how DNA does the job. DNA, the double helix that codes for all the genetic information of  life, does more than make copies of itself. It copies pieces of itself to mRNA, which then travels out of the nucleus and inserts itself into a ribosome.  The ribosome reads the code and then assembles the protein.  The protein is a string of amino acids that curls up into a useful shape.  The protein does its job, and that results in an inherited trait, like eye color, or even hitchhiker's thumb!
Finish up the bugs from class and paste them in your lab books.  If you need a new copy of the handouts, see here: https://docs.google.com/file/d/0B07s3-bcUr7ta0pOVkl1eGR2SXc/edit




ALSO: READ CHAPTER 4, SECTION 2 AND ANSWER THE REVIEW QUESTIONS. 

Mother's Day coming up. Have you thanked her for your DNA?/
