Cornell Notes-Ch 10 DNA and RNA Pg pts

Title at top of Page in Any Color Question in Red. Answer in Blue ink Red ink or Pencil. Summary Goes at the bottom of the page in Green Ink 5 – 7 sentences.

What are Monomers and Polymers? Monomers are small molecules. Polymers are 2 or more monomers bonded together.

What are Nucleic Acids? A type of polymer. 2 types—DNA and RNA Made of monomers called nucleotides. – Nucleotide has 3 parts: Phosphate group Sugar Nitrogenous base – Nucleotides bond together to make long molecules of DNA or RNA.

What is DNA’s purpose? DNA contains all the genetic information for the organism. It determines the traits an organism will have. It does this by coding for the proteins that an organism makes. – That’s all it does----it’s a blue print for proteins

So why are proteins so important? Remember—Enzymes are proteins that are biological catalysts. They control every chemical reaction in living things. DNA controls what enzymes are made, therefore it controls the chemical reactions that make every substance in a living thing. Not all proteins are enzymes Some are structural, meaning they build our bodies. – Keretin (the protein that makes up hair and nails), muscle tissue, hemoglobin(Carries oxygen in red blood cells)

Where is DNA? DNA is located in the nucleus of cells. Draw this

What is the structure DNA? A nucleotide of DNA consists of: 1.Phosphate group 2.Deoxribose sugar 3.1 of 4 nitrogenous bases Adenine(A)Guanine(G)Cytosine(C)Thymine(T)

what is the DNA molecule made of? Double helix (twisted ladder) – 2 strands of sugar/phosphate backbones connected by a pair of bases. – Bases are held together by bonds. Base Pairing Rule=says that complementary bases will always pair together in a DNA molecule. Complementary base pairs – A-T – C-G

RNA A nucleic acid Made in nucleolus Differences from DNA: 1.Ribose sugar 2.Single stranded 3.Uracil(U)-replaces Thymine(T) 4.Shorter than DNA Types: mRNA-messenger RNA rRNA-ribosomal RNA tRNA-transfer RNA Ribose Sugar

What is RNA? A nucleic acid Made in nucleolus Differences from DNA: Ribose sugar Single stranded Uracil(U)-replaces Thymine(T) Shorter than DNA Types: mRNA-messenger RNA rRNA-ribosomal RNA tRNA-transfer RNA

Summary 5 sentences in Green Remember just because you are done with the notes you are not done completely and you do not have your 100 pts until you do the summary: Must be in Green ink.

Do it now Pg. 10 Why is RNA important?

Pg. 11 You will get two worksheets to be taped into this page. – Worksheet one is titled protein synthesis – you will complete this worksheet. – Worksheet two is a virtual lab activity. After you get the first worksheet stamped you can pick up worksheet two. Get both pages stamped for notebook check or you will get a 0 / 200.

Do it again pg. 10 What is the amino acid sequence for a stop codon?

Out pg. 10 If you had 330 amino acids how many codons would you have?

In Pg. 12 Use page 292 in your text book or the worksheet you can find on pg.11 if you followed instructions. You have the following set of letters to match up and translate into RNA then an amino acid: AAG GGC CGC TAT CAT TAC GAG

Do it now Pg. 12 Why are RNA and DNA important to each other? What is one thing that RNA can do that DNA can’t ever do?
