Wednesday 1/4 1. Draw a picture of an RNA molecule. Label as many parts as you can Agenda 1.Finish RNA notes 2.DNA extraction lab 3.RNA worksheet 4.If time start genetic code notes The heck is that thing? 

Question 1) Makes proteins! Question 2) All sorts of things: muscles, blood vessels, digestion, etc

Question 3) What is RNA and how is it similar to DNA? What are some differences? Both are nucleic acids (found in the nucleus) RNA made with ribose rather than deoxyribose Stores information!

Question 4) What is the role of RNA in the cell? Assemble the protein Question 5) Which bases is RNA made of? –Adenine, Cytosine, Guanine, URACIL (ACGU) –No Thymine – Uracil instead Question 6) Which bases match together in RNA? G – C A – U

Question 7) Where in the cell is DNA found, and where is RNA found DNA must stay protected inside nucleus RNA can leave nucleus! How does the cell know which is which?

Question 8) How many strands of RNA? Just one Question 9) What are the 3 types of RNA and what does each do?

3 types of RNA –Messenger RNA (mRNA) a copy of DNA that takes code to ribosomes

–Ribosomal RNA (rRNA) forms the ribosomes ribosomes decode mRNA

–Transfer RNA (tRNA) brings amino acids to ribosome to build proteins

Question 10) mRNA rRNA tRNA

RNA is complementary to DNA –DNA: C A T G T A G C T –mRNA: _ _ _ _ _ _ _ _ _ C – G A – T/U

Jokes! (it’s been too long) What is RNA’s favorite pick up line? I'm not gonna be complete without u.

DNA Extraction Lab When mashing the banana, don’t break the ziplock bag Answer questions on the front as you go Be safe with the centrifuges, use the lid whenever centrifuge is on Do not put banana in the sink, all of it goes into the white tub Clean –The counter at your lab station –The centrifuge tubes –DNA hooks

Could show part of this video, starting at 1:40

The Genetic Code The Code is –t–the sequence of bases in DNA You inherit your Code from your parents The exact proteins you make from the code determine your looks & personality

A codon = 3 bases in a row A codon “codes for” 1 amino acid C A T G G A C T T

1 gene has codons to make 1 specific protein A gene has a start codon & a stop codon
