1 Why is this process important to all living organisms?
Bell Ringer Tuesday  Photosynthesis Respiration Why is this process important to all living organisms? Write the Equation (using words) Write the Equation (scientific formulas) List the reactants of each process List the products of each process What is the main type of energy used or generated from each process? In which cell organelle does each process occur? Does the process require light to occur?

2 Examine the chart and determine how these two processes are related
Examine the chart and determine how these two processes are related. Justify your answer using the data you provided in the chart. 2. Autotrophic organisms could survive on earth easily without heterotrophic organisms, such as humans. Humans could not survive on earth without autotrophic organisms. Defend this claim by drawing a diagram or by using words to defend this claim.

3 DNA Notes

4 Nucleic acids: Draw a nucleic acid below:
Information molecules Nucleic acids: Draw a nucleic acid below:

5 Nucleic acids What are the building blocks of nucleic acids? What makes them different? 5 different nucleotides different nitrogen bases Adenine, Thymine, Cytosine, Guanine, Uracil phosphate sugar N base Nitrogen bases I’m the A,T,C,G or U part!

6 DNA Function of nucleic acids: genetic material stores information
genes blueprint for building proteins DNA  RNA  proteins transfers information blueprint for new cells blueprint for next generation DNA proteins

7 Nucleotide chains RNA: single-sided A, C, G, U DNA: double-sided
nucleotides chained into a polymer phosphate sugar N base RNA: single-sided A, C, G, U DNA: double-sided double helix A, C, G, T phosphate sugar N base strong bonds phosphate sugar N base phosphate sugar N base RNA

8 Where is our hereditary (genetic) information located?
NUCLEUS - Contains genetic material DNA - The genetic material Stores and transmits hereditary information GENES – a segment of DNA that codes for a specific trait

9 Who discovered the structure of DNA?
1. James Watson  American biochemist 2. Francis Crick  British physicist 3. Rosalind Franklin  X-Ray crystallographer 4. Occurred in 1953, Watson & Crick were awarded the Nobel Prize for their work!!!

10 DNA continued… 1. Double-stranded (made up of two strands)
a. Nitrogen bases are held together by hydrogen bonds (weak bond) in the middle of the molecule b. Deoxyribose sugars and phosphates make up the sides of the ladder/molecule held by phosphodiester bonds (strong bonds) c. Antiparallel  run in opposite directions 2. Helix  twisted or coiled

11

12 Nitrogenous Bases PURINES (Pure And Good) 1. Adenine (A)
2. Guanine (G) PYRIMIDINES 3. Thymine (T) 4. Cytosine (C) A or G T or C

13 Chargaff’s Rule Adenine must pair with Thymine
Guanine must pair with Cytosine Their amounts in a given DNA molecule will be about the same. T A G C

14 BASE-PAIRINGS C G H-bonds T A

15 DNA Double Helix is anti-parallel
1 2 3 4 5 S G C T A

16 Genes vs. DNA vs. Chromosomes

17 Create your DNA Glue together nucleotides to create strand of DNA. Include hydrogen bonds (between bases) and phosphodiester bonds (between sugar and base) Answer below questions on separate sheet of paper.

18 Scissors, glue, colored pencils: blue, red, green, orange, yellow

19 10 facts.

20 Closure Differentiate between aerobic and anaerobic respiration. (where is more ATP produced?) What types of organisms do each kind of respiration? What types of organisms produce lactic acid vs. alcohol when using anaerobic respiration? State the cellular respiration equation.

21

22 Knight Time Grab a Chromebook and a lined sheet of paper.
We will be doing Cell transport test corrections in Knight Time today. When finished check with me or if you need explanation on a problem.

23

24 Bell Ringer Objective: Explain the stages of DNA replication.
Draw and label a double helix including the words deoxyribose, phosphate, hydrogen bond, phosphodiester bond, adenine, thymine, guanine, cytosine, nitrogen base, weak bond, strong bond. Define gene.

25 Create your DNA Using the supplies given to you create DNA.
On paper identify what object symbolizes which aspect of DNA. When finished call me over & your group has to explain your work. Required words: adenine, guanine, thymine, cytosine, hydrogen bond, sugar, phosphate, weak bond, nucleic acid, backbone.

26 The Blueprint of Life Individual Yes color the ENTIRE back.
Finished? Hand in and study for quiz tomorrow. We will be starting DNA replication notes soon.

27 DNA Replication DNA must be copied…Why??
The DNA molecule produces 2 IDENTICAL new complementary strands called Daughter strands. Each strand of the original DNA serves as a template for the new strand

28 DNA Replication Occurs with ENZYMES!: Helicase: unzips the DNA
Hydrogen bonds between the nucleotides are broken DNA Polymerase: builds the new DNA strands Matches nucleotides according to base paring rules to the original DNA strands. DNA Template New DNA Parental DNA

29 Copying DNA Replication copy DNA
2 strands of DNA helix are complementary they are matching have one, can build other have one, can rebuild the whole when cells divide, they must duplicate DNA exactly for the new “daughter” cells Why is this a good system?

30 DNA replication Copying DNA
pairing of the bases allows each strand to serve as a pattern for a new strand The greatest understatement in biology! Newly copied strands of DNA

31 Genetic Diversity… Different arrangements of NUCLEOTIDES in a nucleic acid (DNA) provides the key to DIVERSITY among living organisms.

32 The Code of Life… A T C G T A T G C G G…
The “smallest segment ” in which our heredity is stored within our DNA is called the gene. This is how our genetic information is stored; by the sequence of nucleotides that make up a gene. A T C G T A T G C G G…

33 The twisting tale of DNA

34 What did you learn? 1. Why is replication necessary?
2. Describe how replication works. 3. Use the base pairing rules to create the complementary strand: A---? G---? C---? T---?

35 A---T G---C C---G T---A 1. Why is replication necessary?
Meiosis - to pass along our genetic information to our offspring. Mitosis - for Growth, maintenance, and repair. Describe how replication works. Enzymes unzip DNA and complementary nucleotides join each original strand. 3. Use the complementary rule to create the complementary strand: A---T G---C C---G T---A

36 Homework Study for quiz tomorrow
DNA: The Molecule of Heredity Worksheet

37

38 Grab scissors, glue, 2 colored pencils and papers from station#7

39 Demonstrating DNA Replication
Fold construction paper. Glue down and label original DNA Molecule. Complete DNA strand. Left side should be ATGCAC. Color in Deoxyribose (5 carbon sugar). Label phosphate. Put a rectangle around a nucleotide.

40 DNA Helicase does what?

41 The inside – work on back of molecule sheet when finished

42 Create an illustration
Make a cartoon, drawing, poem, song, diagram, etc. to demonstrate DNA replication.

43 Closure Why do we need to replicate DNA?
What is the monomer of carbohydrates? What two ways can nitrogen make its way to the ground? What is the difference between prokaryote and eukaryote?
