1. Review for exam

2. Put levels of organization in order, with pictures DNA, cell, gene, nucleus, chromosome,

4. Create another strand of DNA Where does it happen? Nucleus (dna is a prisoner) A A A C C G T A C T T T G G C A T G

5. Create the strand of mRNA from the DNA Where does it happen? Nucleus (still trapped) A A A C C G T A C U U U G G C A U G

6. rewrite the strand, placing a Guanine where it will cause the greatest impact in the product A A A C C G T A C G U U U G G C A U

7. mRNA is a code for amino acids, which are linked together in the cell organelle ribosome, to create proteins

8. 5 uses for proteins in your body (add the rest to your answer) Create muscle, bone and skin cells Enzymes Antibodies Hormones Cell membranes

9. What does DNA have to do with protein creation? Contains code for amino acids, so protein will be made

10. Mitosis Type of cell Body cell # chromosomes that start process 2n # chromosomes in cell that is created 2n Diploid or haploid diploid

11. Mitosis sketch 46

12. Meiosis Type of cell Gamete (or…..) Reproductive cell # chromosomes that start process n # chromosomes in cell that is created n Diploid or haploid haploid

13. meiosis sketch 46

14. 3 causes of mutations radiation (tanning beds, xrays) Chemicals (mercury, benzene) Unknown

15. What type of cell would a mutation have greatest affect on next generation? Arm or eye or stomach or…… no no no Gamete ; because you reproduce with them, which is passing trait to next generation

16. DNA Building block is Sugars, phosphates and nitrogen bases One function Code for proteins

17. Protein Building block is Amino acids One function Enzymes, etc.

18. Carbs Building block is Sugars (monosaccharide or glucose), One function Energy (ATP)

19. Fats Building block is lipids One function Insulation, energy

20. Make sure you know answers to Down’s syndrome essay in Reebop Unit exam on Monday, unless you have lots and lots of good questions for me on Monday…. Then test will be Tuesday.
