1. DO NOW
You have ten minutes to finish up the graphing assessment from yesterday. I will call you by name to receive your packet.
If you are done before the ten minutes is up… start reading in the text on pg 135

2. RNA
The Other Nucleic Acid

3. DNA: Review Double stranded molecule Nucleotides = monomer
base, phosphate, and deoxyribose
Follows the base pair rule
A and T
C and G
Contains the instruction manual for an organisms traits
Contained in the nucleus of a cell

4. Genes Code within DNA for the traits of the organism
Sequence of bases on DNA
One gene = one protein… proteins determine traits
Different proteins are determined by the different sequences of bases
Ex/ CATCAT = purple hair, TACTAC = yellow hair

5. An analogy… Think of the BASES as LETTERS LETTERS form WORDS (genes)
WORDS form SENTENCES (the traits of an organism)
Endless combinations to form all living variations

6. DNA cannot do it alone! DNA trapped in the nucleus…
Needs help getting the code out of the DNA and create protein
RNA to the rescue!

7. RNA Ribonucleic Acid Single stranded Nucleotides = monomers
Base (A, C, G, U), phosphate, ribose
Follows base pair rule, except no thymine… uses URACIL instead
DNA: A T A G C G
RNA:

8. Function of RNA
Carry and translate the message (code) in the DNA to make proteins
2 Types of RNA needed
mRNA
Messenger RNA: gets the code out of the nucleus
tRNA
Transfer RNA: translates the code into a protein

9. RNA vs. DNA structure

10. Amoeba Sisters: DNA vs. RNA
