1 G A G T GG C A T CC T A C G A G T GG C A T CC T A C Sugar- Phosphate Backbone Hydrogen Bond NEXT

2 G A G T GG C A T CC T A C G A G T GG C A T CC T A C DNA Polymerase DNA Helicase RNA Polymerase 1. Click the correct enzyme above that will unzip the DNA molecule to begin replication…

3 Try Again…. Think….what is the structure or shape of DNA called… then look at the enzymes again and look for the one that sounds like that structure… Back

4 Try Again…. Think….aren’t you making more DNA? That should probably have the name in the enzyme…and what is the structure or shape of DNA called… then look at the enzymes again and look for the one that sounds like that structure… Back

5 Good Job!!! DNA Helicase DNA HELICASE is the enzyme that will unzip the DNA molecule to start the process of replication of DNA…. Next Step….

6 G A G T G G C A T C C T A C G A G T G G C A T C C T A C 2.DNA Helicase unzips the DNA molecule….but where? At Nucleotides At Backbone At Nitrogen Bases At Hydrogen Bonds

7 Try Again…. Think….the two strands of DNA are held together at the nitrogen bases…what holds the nitrogen bases together? Back

8 Good Job!!! DNA Helicase breaks the HYDROGEN BONDS between the nitrogen bases so that the two strands can be separated… Next Step…. At Hydrogen Bonds

11 G A G T GG C A T CC T A C G A G T GG C A T CC T A C Now that the DNA strands are separated, freely floating nitrogen bases in the nucleus will attach to their compliment pairs on the DNA strands. T G C A NEXT

12 To begin the replication process, attach the correct nitrogen bases to the DNA strand on the left… G A G T GG C A T CC T A C G A G T GG C A T CC T A C T A G C C T G A C C C C C C T T TT A A A A G G G G G G

27 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C GG G G Next Step….

28 Good Job!!! You finished one side of the DNA strand… but remember both sides must be replicated to create new DNA…so now complete the right side. BUT when this happens on the other side of the DNA molecule, it goes in reverse….bottom to top! So start at the bottom this time on the right side… Next Step….

29 Now, attach the correct nitrogen bases to the DNA strand on the right to complete the replication process… G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C G G C C C T T A A G G G

39 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G Almost done…

40 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G Few more…

41 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G

42 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G One more…

43 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G DONE! But….we are missing the backbones….. Next Step….

44 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G What enzyme will help create the new backbones for these DNA strands? Choose correct one on right… DNA Polymerase DNA Helicase RNA Polymerase

45 Try Again…. If DNA Helicase broke the double helix apart…it has to be a different enzyme that rebuilds the DNA backbone and makes corrections if needed… Back

46 Try Again…. Close…..Think….aren’t you making more DNA? That should probably have the name in the name of the enzyme. Back

47 Good Job!!! DNA POLYMERASE is the enzyme that will rebuild the DNA backbones and make any corrections if there are mistakes… Next Step…. DNA Polymerase

48 2.But what is built in the DNA backbone? Nucleotides Nitrogen bases Deoxyribose Sugar & Phosphate G A G T G G C A T C C T A C G A G T G G C A T C C T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G

49 Try Again…. The nitrogen bases are the “steps” of the “ladder”. They are already in place… Back

50 Try Again…. The nucleotide remember consists of 3 parts: Sugar, phosphate, and nitrogen bases. You already added nitrogen bases….so closer…. Back

51 Good Job!!! Once the new nitrogen bases come in on the replicated strands, the DNA Polymerase enzyme will rebuild the backbone of Deoxyribose Sugar and Phosphate! Next Step…. Deoxyribose Sugar & Phosphate

52 G A G T GG C A T CC T A C G A G T GG C A T CC T A C T T T A A G C A C G G C T A C C C T T A A G C C G G G G Old Strand New Strand Old Strand New Strand END RESULT? Two new strands of DNA… Both look identical to the original DNA… But one side of the new DNA is made of the old strand… The other side is made of the new strand…
