  1. Welcome to

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

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

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

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

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

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

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