DNA: THE ALAPHABET OF LIFE

CREATED BY CHRIS WOODS


Slide2 l.jpg

DNA

DEOXYRIBONUCLEIC ACID

STORES AND PASSES ON GENETIC INFORMATION FROM ONE GENERATION TO ANOTHER .


Slide3 l.jpg

DNA STRUCTURE

THE DNA STRUCTURE IS SHAPED LIKED A SPIRAL STAIRCASE, OR

TWISTED LADDER.


Slide4 l.jpg

DNA STRUCTURE

THE OUTER PARTS OF THE OF THE LADDER ARE MADE OF SUGARS.


Slide5 l.jpg

DNA STRUCTURE

THE STEPS OF THE LADDER ARE MADE OF PAIRS OF NITROGEN BASES.


Slide6 l.jpg

DNA STRUCTURE

  • ADENINE = A

  • GUANINE = G

  • CYTOSINE = C

  • THYMINE = T

  • THEY ARE REPRESENTED BY

  • THEIR CAPITAL LETTER.


Slide7 l.jpg

DNA STRUCTURE

THERE IS ONLY ONE WAY THE NITROGEN BASES CAN FORM

ADENINE PAIRS WITH THYMINE

GUANINE PAIRS WITH CYTOSINE


Slide8 l.jpg

DNA STRUCTURE

QUESTION ?

CAN C JOIN WITH A

AND G JOIN WITH T

YES

NO

DNA STRUCTURE

ACTCATGGTCATG

TGAGTACCAGTAC

THIS IS AN EXAMPLE OF A GENETIC CODE THAT MAY BE FOUND IN YOUR BODY.


Slide12 l.jpg

DNA STRUCTURE

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


Slide13 l.jpg

DNA STRUCTURE

BECAUSE THERE CAN BE SO MANY DIFFERENT COMBINATIONIS OF THE BASES THE CODE CAN BE LIMITLESS


Slide14 l.jpg

DNA STRUCTURE

EXAMPLE:

ATCGTCAGG MAY BE FOR HAIR

COLOR.

BUT

ATCGTCAGC MAY BE FOR EYE

COLOR


Slide15 l.jpg

DNA REPLICATION

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


Slide16 l.jpg

DNA REPLICATION

  • THE LADDER SPLITS

2. FREE FLOATING NITROGEN BASES BEGIN TO PAIR WITH EACH STRAND

3. TWO NEW DNA CHAINS ARE FORMED
