Do Now: DO You Remember?... Describe the shape of DNA.
What enzyme unwinds and unzips DNA to make RNA?
Explain how you think a cut heals.
1Guide to Taking NotesBe sure to write down the essential questions.Focus on what is in red. Anything in red is Must to copy in your journal.Green is optionalBlue is mostly for refocusing or titled.Try to use the same formatting as shown.
Unit 2: Genetics and BiotechnologyUnit Essential Question: What is DNA and how does it carry the coded instructions that allow cells to function properly?
Chunk #2: Generation to GenerationConcepts:1.) Cell Cycle2.) Mitosis3.) Meiosis
Work for the Week:3/31 4/4Formative:Do Now(s) 15pts.Exit Tickets vary.Onion Root Computer Lab 30pts.Mitosis w/Yarn Lab 50pts.Mr. Potato Head Lab 50pts.
Summative:Mitosis Quiz 20pts.Meiosis Quiz 20pts.
Lesson #1: Cell Cycle: Transmission of Genetic Information
LEQ: What is the process of cellular growth?
Big Idea: Cells Reproduce.All cells must go through some phase of reproduction in order to grow.
Most cells go through a life cycle.Two main phases:InterphaseExpansionMitosisDivision
7Big Idea: A cell must expand before it divides.
Interphase:3 sub phases:G1 (First Growth) Cell grows rapidly. Biggest part of interphase.S (Synthesis) DNA Replication occurs. Chromosomes become chromatids.G2 (Second Growth) Prepare for division.
8Match It Up!!For each phase that is described1. Lay out the Title2. Place the picture underneath
Big Idea: There is order in the division. _______________________________.
Mitosis: Nucelar Division4 sub phases:Prophase Nuclear envelope dissolves. Chromatids condense and pair up and Spindle Fibers Form
10Draw It Up!!For the phase you just matchedDraw it in your journal/notebook
Mitosis: Nucelar Division4 sub phases:Metaphase Chromatids line up along the metaphesial plate (middle line)
Big Idea: There is order in the division. ____________________________12Draw It Up!!For the phase you just matchedDraw it in your journal/notebook
Mitosis: Nucelar Division4 sub phases:Anaphase Spindle fibers pull apart the chromatids at the centromere and the chromosomes move to opposite poles of the cell.
Big Idea: There is order in the division. ____________________________14Draw It Up!!For the phase you just matchedDraw it in your journal/notebook
Big Idea: There is order in the division. ____________________________
Mitosis: Nucelar Division4 sub phases:Telophase Nuclear envelope appears at the pole and chromosomes uncondensed.
16Big Idea: There is order in the division. One to Two!!
Cytokinesis:Cytoplasm splitsCell Membrane is pinched in half to enclose each cell.Cleavage Furrow
17Lets Find OutWhat phase of the cell cycle does a cell spend most of its time?
Grab a laptop and pair upGo to the following website:http://www.biology.arizona.edu/DEFAULT.html
Exit TicketThis is worth 10pts.Place in bin when done
Be sure your name and class period are noted on the ticket.
See You Next Time!!

Mitosis Worksheet23Big Idea: Cells have a series of Red Light Green Light Switches that regulate feedback information.
Checkpoints:G1 Cell growth CheckpointDetermines if the cell should divideAKA: The Resting PeriodSome Muscle & Most Nerve Cells are in this.G2 DNA synthesis CheckpointDNA Replication gets checked by certain enzymesM Mitosis CheckpointGets triggered at the end of MitosisPrompts cell into G1
24Big Idea: Sometimes a Cell can lose control.
Cancer:Uncontrolled Cell GrowthDisorder of Cell Division
25Lesson #1b: Cell Cycle: Transmission of Genetic Information
LEQ: What does the process of cellular growth involve?
Mitosis Lab: Karyotype
Big Idea: DNA is tightly winded (coiled) in the nucleus.DNA is very, very, very loooooong!!
Chromosomes:Made up of DNA and protein.Condensed packages of DNA.Vary in sizeContain all genetic information of an organism
29Big Idea: When chromosomes pair up an X formation is shown.This ensures that the genetic information remains intact.
30Big Idea: Chromosomes are only seen during divisionMakes it easy for a cell to divide
During prophase, just before metaphase is when you can clearly see the chromosomes.Scientists suspend cells in this phase in order to read the overall genetic viability of a person: Karyotyping
31Karyotyping!!
Organizing Chromosomes to determine ones genetic composition.32

Lesson #2: Cell Cycle: Transmission of Genetic Information
LEQ: What processes allow genetic information to differ?
Big Idea: There are two types of cells.Not all cells divide at the same rate.
Gametes: Sex CellsFound only in sex organsInclude:Ovaries (Eggs/Ova)Testes (Sperm)Haploid Chromosome Number, nUndergo Meiosis
Somatic: Body CellsMajorityConsist of:
Diploid Twice the Chromosome Number, 2nUndergo Mitosis
MuscleSkinBrainFat, etc.38PUT ALL ELECTRONICS AWAY
102 46 48 1260Big Idea: Body Cells have twice the amount of chromosomes than Sex Cells.More Body not enough SexCells that is
This is called the Diploid NumberThis number varies for organisms but are consistent for their species.

Haploid/Diploid Worksheet42Lesson #2: Cell Cycle: Transmission of Genetic Information
LEQ: What processes allow genetic information to differ?
Big Idea: Sex Cells undergo division twice.They end up with half of the Diploid Number
This is called the Haploid NumberOnly seen in sexual reproductive organisms.
44Big Idea: Sex Cells undergo division twice.They end up with half of the Diploid Number
Meiosis: Specialized Nuclear DivisionThe process of creating gametes (sex cells)SporesSpermOvaInvolves 2 divisions:Meiosis IMeiosis II
45Big Idea: Sex Cells undergo division twice.They end up with half of the Diploid Number
Meiosis: Specialized Nuclear DivisionLike Mitosis includes the following phases:
Prophase IProphase IIMetaphase IMetaphase IIAnaphase IAnaphase IITelophase ITelophase II46Big Idea: Sex Cells undergo division twice.
47Big Idea: There is too much information to pass on.
Meiosis I: Rewriting PeriodAKA: Primary DivisionCrossing Over occurs during this periodChromatids exchange informationHappens during Prophase ITWO Daughter Cells that are different2n 2 2n
Information gets rewritten and new versions are created.48Big Idea: There is too much information to pass on.Information gets rewritten and new versions are created.
Meiosis II: Separation PeriodAKA: Secondary DivisionIndependent AssortmentAlignment during metaphase is randomFOUR Daughter Cells that are different2 2n n, n, n, n
