2. CREATED BY CHRIS WOODS

3. STORES AND PASSES ON GENETIC INFORMATION FROM ONE GENERATION TO ANOTHER. DNA DEOXYRIBONUCLEIC ACID

4. DNA STRUCTURE THE DNA STRUCTURE IS SHAPED LIKED A SPIRAL STAIRCASE, OR TWISTED LADDER.

5. DNA STRUCTURE THE OUTER PARTS OF THE OF THE LADDER ARE MADE OF SUGARS.

6. DNA STRUCTURE THE STEPS OF THE LADDER ARE MADE OF PAIRS OF NITROGEN BASES.

7. DNA STRUCTURE 1.ADENINE = A 2.GUANINE = G 3.CYTOSINE = C 4.THYMINE = T THEY ARE REPRESENTED BY THEIR CAPITAL LETTER.

8. DNA STRUCTURE THERE IS ONLY ONE WAY THE NITROGEN BASES CAN FORM ADENINE PAIRS WITH THYMINE GUANINE PAIRS WITH CYTOSINE

9. DNA STRUCTURE QUESTION ? CAN C JOIN WITH A AND G JOIN WITH T YES NO

10. CORRECT MOVE ON

11. SORRY REVIEW MORE

12. DNA STRUCTURE ACTCATGGTCATG TGAGTACCAGTAC THIS IS AN EXAMPLE OF A GENETIC CODE THAT MAY BE FOUND IN YOUR BODY.

13. DNA STRUCTURE THE COMBINATIONS OF THE NITROGEN BASES IS THE CODE THAT PRODUCES THE GENES FOR A PARTICULAR TRAIT.

14. DNA STRUCTURE BECAUSE THERE CAN BE SO MANY DIFFERENT COMBINATIONIS OF THE BASES THE CODE CAN BE LIMITLESS

15. DNA STRUCTURE EXAMPLE: ATCGTCAGG MAY BE FOR HAIR COLOR. BUT ATCGTCAGC MAY BE FOR EYE COLOR

16. DNA REPLICATION REPLICATION: IS THE PROCESS WHERE DNA MOLECULES FORM EXACT DUPLICATS.

17. DNA REPLICATION 1.THE LADDER SPLITS 2. FREE FLOATING NITROGEN BASES BEGIN TO PAIR WITH EACH STRAND 3. TWO NEW DNA CHAINS ARE FORMED
