1 RNA & Central Dogma

2 BELLWORK - HAVE SLATE, MARKER & ERASER ON DESK 1. What does DNA stand for? 2. Based on your answer to #1, predict what RNA stands for? 3.What is the complementary DNA strand to this sequence GTA ATC ATA? 4.Draw and label a picture of a nucleotide. 5.Who are Watson & Crick & what do they have to do with DNA?

3 Announcements Bio 1-2: Is your science fair board turned in? PreAP: BLAST handout get ratHBB from class home DietrichBiology.wikispaces.com due date changed to next Tues Everyone: This is a block week, so Friday is…. Everyone: Pass out slates for today

4 Central Dogma (Big Idea) of Biology DNA RNA Protein DNA stores information to run cell

5 DNA vs RNA Deoxyribonucleic Acid How many nucleotides? 3 parts of a nucleotide? What does the B stand for?

6 DNA vs RNA Deoxyribonucleic Acid How many nucleotides? 3 parts of a nucleotide? What does the B stand for? Ribonucleic Acid Whats the difference? OH!

7 Remember this? Structure is related to function! What are DNAs 2 functions?

8 RNA Structure Notes RIBOSE is the sugar in RNA nucleotides (instead of deoxyribose)

9 RNA Structure Notes RIBOSE is the sugar in RNA nucleotides (instead of deoxyribose) In RNA, the nitrogenous bases are G,C,A and U (no T)

10 RNA Structure Notes RIBOSE is the sugar in RNA nucleotides (instead of deoxyribose) In RNA, the nitrogenous bases are G,C,A and U (no T) RNA is usually single- stranded

11 Vote by sign language: DNA AGCCTGCTA TCGGACGAT RNA NA

12 Try this What might it look like if you turned this double stranded DNA molecule into an RNA copy? AGTTCGA TCAAGCT RNA: UCAAGCU Which DNA strand would this RNA be the COMPLEMENT of?

13 Try this What might it look like if you turned this double stranded DNA molecule into an RNA copy? AGTTCGA TCAAGCT RNA: UCAAGCU Which DNA strand would this RNA be the COMPLEMENT of? Do the RNA complement for the bottom DNA strand AGUUCGA

14 DNA vs RNA RNA has a different structure… predict its functions (jobs) Hint: other names for RNA messenger RNA ribosomal RNA transfer RNA

15 Central Dogma (Big Idea) of Biology DNA RNA Protein DNA stores information to run cell RNAs function is to make proteins!

16 Why are proteins so important? Proteins are made of tiny subunits…what are they called? What are some functions of proteins? (Hint: ) Chemical Reactions (enzymes) Immune System (antibodies) Growth & Development (hormones) etc.

17 Central Dogma (Big Idea) of Biology DNA RNA Protein DNA stores information to run cell Proteins actually DO the work in the cell RNAs function is to make proteins!

18 Types of RNA mRNA: messenger RNA makes a copy (message) of the information stored in DNA & moves the info out of the nucleus! (DNA doesnt leave nucleus) Codons are 3 letter words that make up the message- its a recipe for a protein

19 Types of RNA rRNA: ribosomal RNA folds into a ribosome which reads the mRNA codons and connects amino acids into a chain that will become a protein rRNA folds into 2 subunits (large & small) Together, they make the ribosome! Realistic image of rRNA folded into a ribosome

20 Types of RNA tRNA: transfer RNA transports amino acids to the ribosome, and uses an anti-codon to match the correct amino acid to the correct mRNA codon. It then transfers amino acids to the growing chain. tRNA is T-shaped!

21 Closure- Structure & Function of DNA & RNA DNARNA
