3. DEOXYRIBONUCLEIC ACID
The Double Helix

4. Why does DNA replicate?
Cells copy genetic information before cell division so that each new cell has a complete set of DNA

5. 3 steps to DNA Replication
UNZIP: DNA Helicase
“unzips” the strands of DNA breaking the hydrogen bonds.

6. 2) BASE PAIRING: DNA Polymerase bonds free nucleotides with nucleotides from parent strand

7. 3. Joining Nucleotides: Ligase bonds nucleotides together.
This result in 2 identical DNA molecules.

8. Semi Conservative Replication:
New DNA molecule contains 1 new strand and 1 old strand.

13. Protein Synthesis occurs in two steps: 1) Transcription: DNA RNA 2) Translation: RNA Protein

14. Makes a temporary copy of DNA

15. Essential Question: How is a protein made using the code of nucleotides from DNA?

16. Turn to a Partner
List all the similarities and differences with DNA and RNA

17. RNA Structure RNA differs from DNA in 3 ways: RNA is a single strand
RNA has the sugar ribose
RNA has the nitrogen base uracil instead of thymine.

18. 3 Types of RNA
Messenger RNA (mRNA)
Carries copy of instructions for making protein from nucleus to ribosome

19. 2. Ribosomal RNA (rRNA)
Structural component of ribosomes

20. 3. Transfer RNA (tRNA)
Transfers an amino acid to the ribosome

21. Talk to a Partner
List the 3 types of RNA & their functions

22. 4 steps to Transcription:
An enzyme unzips DNA
As DNA unzips, free RNA nucleotides pair with the DNA nucleotides.
When base pairing is done, the new mRNA breaks away.
mRNA leaves the nucleus and enters the cytoplasm

29. 4 Steps to Translation

30. Transfer RNA (tRNA)
Transfers an amino acid to the ribosome

31. mRNA attaches to the ribosome.
2. The tRNA molecule with the correct anticodon attaches to the mRNA codon.

32. ***This process continues until a STOP codon is reached.
3.The mRNA slides through the ribosome to the next codon and another tRNA comes and attaches to mRNA.
4. The 1st tRNA releases its amino acid to attach to the 2nd amino acid using a peptide bond.
***This process continues until a STOP codon is reached.

37. Translation into a Protein
Proteins are made by joining amino acids with a peptide bond into long chains called polypeptides.
The genetic code is read three letters at a time, so that each “word” of the coded message is three mRNA bases long.
This 3-letter “word” is known as a codon.
Each codon corresponds to a particular amino acid (the anti-codon on tRNA).
