Nucleic Acid: A large molecule like DNA and RNA made up of smaller molecules called nucleotides. Nucleotides: Small molecules made up of a sugar, a nitrogen base, and phosphate Nucleotides: Small molecules made up of a sugar, a nitrogen base, and phosphate Nucleic acids are what our DNA or genetic material and RNA are made of Nucleic acids are what our DNA or genetic material and RNA are made of With out nucleic acids our body would not have directions and could not function. With out nucleic acids our body would not have directions and could not function.

NUCLEOTIDE (building block of nucleic acids)
7
Similarities and differences between DNA and RNA (pages 362-363)
9
Why do we need RNA? DNA cannot leave the nucleus DNA gets transcribed into Messenger RNA (mRNA) Once edited, mRNA can leave the nucleus as a single strand http://www.pbs.org/wgbh/nova/body/rnai.html
10
Conection between DNA and Protein DNA defines the genotype (genetic makeup) Proteins determine the phenotype (specific trait) Each gene codes for one protein (polypeptide)

13
DNA to Protein Connection Geneticists Beadle and Tatum studied mutant strain of orange mold This strain was missing a necessary enzyme for mold to grow Each mutant strain was defective in a single gene One gene-on enzyme hypothesis More accurate – One gene one polypeptide http://www.youtube.com/watch?v=vIrrtM47Wio 9:33-12:00
14
Life is orchestrated by Proteins Proteins Combinations of 20 different amino acids linked in long chains Function is determined by amino acid sequence Amino acid sequence is determined by DNA sequence Used for enzymes, hair, muscles, cell parts
15
Amino Acids Linked Amino Acids Link Together to Form a Protein (Polypeptide)
16
Protein Synthesis THE CENTRAL DOGMA OF BIOLOGY DNA → RNA → Protein (polypeptide) This happens in two main steps: Transcription RNA synthesis RNA editing Translation
17
Transcription Transcription occurs inside the nucleus of the cells! The main transcription players are: DNA Messenger RNA (mRNA) RNA polymerase

32
Information is sent from the Nucleus to ribosome where protein is made
33
Outline of Protein Synthesis Directions on DNA DNA opens up and messenger RNA (mRNA) copies message mRNA is edited – some parts taken out (introns) mRNA goes out of nucleus to ribosome mRNA attaches to ribosome Transfer RNA (tRNA) picks up an amino acid tRNA attaches to mRNA matching complementary base pairs at opposite end from amino acid Amino acid is attached to other amino acids held by the ribosome to make a chain of protein When protein completely built, it separates from ribosome
34
MONDAY 3-21-16 LEARNING OBJECTIVE: UNDERSTANDING HOW THE CODONS CODE FOR AMINO ACIDS DURING TRANSLATION ENTRY TASK: WHAT IS THE DIFFERENCE BETWEEN A CODON AND ANTICODON?
35
PLAN OF THE DAY TRANSLATION OF THE mRNA INTO AMINO ACIDS FINISH TRANSCRIPTION NOTES AND PRACTICE QUIZ PRACTICE TRANSCRIPTION AND TRANSLATION WITH DIAGRAM AND DRY ERASE MARKERS
36
HOMEWORK DUE TOMORROW READ AND NOTES OF SECTION 13.3 MUTATIONS (PAGES 372-376)
37
1.A sequence of nucleotides In DNA (a gene) is transcribed to RNA in the nucleus 2. The RNA travels to the cytoplasm where it is translated into the specific amino acid sequece of a polypeptid
39
A codon is a three-base "word" that codes for one amino acid. Several codons form a "sentence" that translates into a polypeptide.

46
Practice translating codons into amino acids DNA (3 letter) ATGATACAACACATCCAGTAG mRNA codon tRNA anticodon Amino acid
47
PROTEIN SYNTHESIS AND WORDS ACTIVITY 1.One person in your group will go to the nucleus (front desk) and select a card 2.Write the template # on your paper and the DNA template sequence (three bases/letters per box) 3.WITHOUT LEAVING THE ‘NUCLEUS’ transcribe the DNA message into mRNA (complementary bases, remember about uracil!!) 4.Now you can go ‘outside the nucleus’ and go back to your desk where the tRNA will write the anticodon sequence from the mRNA codons 5.Once you have this last sequence, you can go around the room to hunt for the anticodons to decipher your message 6.Bring your message to me when done to check if correct. If correct, you can get another card to decipher. If not, correct your error to get the right message
