1. DNA: THE ALPHABET OF LIFE

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

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

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

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

6. DNA STRUCTURE ADENINE = A GUANINE = G CYTOSINE = C THYMINE = T
THEY ARE REPRESENTED BY
THEIR CAPITAL LETTER.

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

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

9. CORRECT

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

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

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

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

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

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