September 27 – October 1

Dear Students:
This week you will have a test on Chapter 4. Please read the Chapter first and then use your section summaries to review. Your class notes and work pack are also useful and available for you to review. Your test is Wednesday, September 29.
Your DNA structure project is due Friday, October 1st. DNA (Deoxyribonucleic acid) is a nucleic acid, or large molecule, that contains the genetic code or blueprint used in the creation of all living organisms and some viruses. DNA pieces are called genes. DNA comprises two long polymer strands called nucleotides, each with a backbone of sugars and phosphates. The backbone sugars are joined to rungs of two of four molecules called bases, which pair up as adenine and thymine, and guanine and cytosine. It is this sequence of four bases that actually encodes genetic information. Making DNA models is simple and can be done with household items.
Don’t forget to present your rubric with your project!!
