Warm UpName the modes of inheritance.If a person has the genotypes IA IA or IA I, what blood type do they have?When there are only 3 phenotypes in an organism, what are the possible types of inheritance?AgendaObjective: SWBAT: identify that DNA is made up of the nucleotides adenine, guanine, cytosine, and thymineGo over Quizzes and options to improve your gradeKWL Chart on DNADNA ActivityApproximately 20 minutes to work on corrections

Notebooks: please turn them in at the end of class todayQuizzesHand backPass out cheat sheetOptions for improving gradeRetake (You would have to come in after school or during lunch)Corrections (You will have an opportunity to start during class today)

Correction ExampleMom is heterozygous for Type A blood. Dad has type AB blood. What possible blood types could their children inherit? (2 points)

Based on the Punnett Square, there are three different possibilities. If a person has a genotype of IA IA or IA i, then they have type A blood. If a person has IB i then they have type B blood. Finally if a person has IA IB then the person has type AB blood. That means these parents could have a child with Type A, B or AB blood. Another exampleHuman height and weight are determined by multiple different genes. As a result, there is a wide variety of heights and weights for people to express. What type of inheritance is this? (incomplete, co-dominance, multiple alleles, polygenic, sex-linked)? (1 point)

Say I put down that it was incomplete dominance. I would explain that its actually polygenic because the problem says both traits are determined by multiple genes. Polygenic literally means many genes. KWL ChartWhat do we already know about DNA?Its a type of nucleic acidIt stands for Deoxyribonucleic AcidDNA is found in all cellsIn Eukaryotic cells, DNA is found in the nucleusIt carries our genetic information and determines our traitsSegments of DNA are called genesDNA is bundled up into chromosomes8Why is DNA important?DNA contains our genetic informationDNA is a set of instructions within the cell for making proteinsProteins determine just about everything about youWhether you are lactose intolerantWhat skin color you haveYour eye colorControl the rate of reactions in our body

Warm upDirections: Unless I tell you otherwise, you do not have to copy the questions anymore But you need to date every warm up.

Name at least two reasons why DNA is important. Write in complete sentences.AgendaObjectives: SWBAT: identify that DNA is made up of nucleotides that follow the base pairing rule AND compare and contrast DNA and RNA by creating a chartFinish Building DNA ActivityNotesExit TicketWork on Quiz Corrections

AnnouncementsQuiz Corrections are due tomorrow. You will get a little time at the end of class to work and ask me questions.You can come in to retake, or take the quiz for the first time, during lunch or after schoolFor warm-ups you will not always get a stamp if you simply finished the warm up. I will start checking for correct answers.

DNA building activityWhat is the Structure of DNA?Deoxyribonucleic Acid or DNA looks like a twisted ladder or double helix

Its made up of subunits called nucleotides

-Each nucleotide has a sugar, a phosphate and a nitrogen base

14Label the parts on your copy:

PhosphateSugarNitrogen BaseHydrogen BondsDNA has the sugar deoxyribose D for deoxyribose15Types of Nitrogen BasesThere are 4 types of nitrogen bases in DNAA= AdenineT= ThymineC= CytosineG= GuanineNitrogen bases connect the 2 strands of DNA together, like the rungs (steps) of a ladder16Exit TicketEach nucleotide has a ________, ____________ and ___________ ________

If one strand of DNA was ACTACTGGG, what would be the complimentary strand?Warm UpGive yourself a rating for each one of the following categories. Be honest. AgendaObjectives: SWBAT: compare and contrast DNA and RNA by creating a chart AND Describe that replication is when DNA makes a copy of itself.Comparison ChartColoring and Labeling ActivityVideoWhite Board Activity ( If we have time)Exit TicketReminder: Turn in your quiz corrections. Friday is the last day to do a retake.

DNAContains all our genetic informationIs made up of subunits called ______________Each subunit contains a phosphate, _________ and _______________ _________

Base PairingNitrogen bases pair up to make the steps of the ladder

In DNA -A always pairs with T And-C always pairs with G21Complementary StrandsEach strand of DNA is complimentary to the otherThat means that each strands nitrogen bases match up (A - T, C - G)

Example: If the code on one strand of DNA is ACGTC, then the complimentary strand would be TGCAG22Practice Problems: Write the Complimentary Strand1. ATCGC

2. TGCAGA

3. CCCGTACGTA

4. TAGTGACTAGC

23RNARNA is another type of nucleic acid thats found in the nucleus and cytoplasm of a cell

Unlike DNA, RNA is made up of only one strand of nucleotides

24Difference in Nitrogen BasesInstead of having the base thymine, RNA has the base uracilThat means when RNA is formed, adenine pairs with uracil (A - U)

25SugarsOne main difference between RNA and DNA is that they are made up of different sugars-RNA has the sugar ribose-DNA has the sugar deoxyribose

26DNA vs. RNADNARNA27DNA vs. RNAFound in the nucleusFound in the nucleus and cytoplasmDouble-stranded(double helix)Single-strandedDeoxyribose sugarRibose sugar A pairs with TA pairs with UT pairs with AU pairs with A28

You will have 10 minutes to color in your molecule of DNA and strand of mRNA.Create a key that shows me which shape represents each base.Make each base a different color29Warm UpName the 4 nitrogen bases of DNAIf a strand of DNA has the bases AATGGCTCA, what would the complimentary strand look like?What is one difference between DNA and RNAAgendaObjectives: SWBAT explain that replication, transcription and translation are codependent processes that ultimately make proteins AND In transcription, a strand of mRNA is created from a strand of DNA with uracil replacing thymine.

35EnzymesEnzymes are responsible for unzipping the DNA and adding the bases to form the 2 new molecules.

Enzymes are proteins in our cells. They help regulate chemical reactions in our body.

Helicases are enzymes that split the DNA and DNA polymerase adds the bases

Proteins help make proteins!36White Board Practice1.Whats missing in this nucleotide?deoxyribose + phosphate + _________382What type of sugar does RNA have?393What are the subunits that make up DNA and RNA called?404A stands for what?

C stands for what?415.A pairs with ____

C pairs with ____426.G stands for what?

T stands for what?437(DNA or RNA)_________ is made up of 2 strands of nucleotides.448If the code of bases on one strand of DNA is AGCCTAGG, then what is the code on the complimentary strand?459What is the process that makes a copy of DNA? 4610In RNA, Thymine is replaced with ________11Is this a strand of DNA or RNA?

AGCCGUUAUGCGAUImportance of DNADNA is responsible for providing instructions to make proteins.

Proteins are responsible for the expression of our genes.

Ex. A protein is responsible for the amount of melanin in your skin. The more melanin you have, the darker your skin is.

49How are proteins made?In order to make proteins, 3 processes must occur

DNA Replication (makes DNA)Transcription (makes mRNA)Translation (makes proteins)

50What happens during Transcription?A strand of messenger RNA (mRNA) is made using DNA as a template.51What happens during Transcription?One strand of the DNA is the templateNitrogen bases attach to the DNA by following the base pairing rule except U will replace TThe sequence (order of the nitrogen bases) of RNA depends on the strand of DNAExample:A-C-C-A-A-AU-G-G-U-U-U52demomRNAJust like DNA is split up into segments called genes, a strand of mRNA is split up into sections called codons.

Codons are words of mRNA that are made up of three nitrogen bases. Example: AUC or GGU

Codons code for amino acids that make up proteins
