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

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

4. DNA
STRUCTURE
THE OUTER PARTS OF THE 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
1. ADENINE = A
2. GUANINE = G
3. CYTOSINE = C
4. 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
1. THE LADDER SPLITS
2. FREE FLOATING NITROGEN
BASES BEGIN TO PAIR WITH
EACH STRAND
3. TWO NEW DNA CHAINS ARE
FORMED
