1. Pick up a concept map and start working
Day 07
Warm up
Pick up a concept map and start working

2. The 4 nitrogen bases are:
DNA Structure and Function Study Guide
Function is to store
Stands for
DNA
Genetic Information
Deoxyribonucleic Acid
Found in all
Model of DNA was developed by:
Made up of repeating sub-units called
but only in the
Watson and Crick
Cells
Nucleus
of eukaryotes
Looks like a “twisted ladder” or
Nucleotides
Sides of the ladder are made up of alternating
Double Helix
which have 3 parparts:
Phosphates and sugars
The rungs or “steps” of the ladder are made up of
Nitrogenous Bases
The 4 nitrogen bases are:
Hydrogen Bonds
Form between bases
Base Pairing Rules :
Guanine only pairs with
Adenine only pairs with
Thymine
Cytosine

3. Page: 31 Title: Transcription EQ: How are DNA and mRNA involved in the process of transcription? Standard: Explain the purpose and process of transcription and translation using models of DNA and RNA.[BIO.6C]

4. Only dealing with this part today!
Central Dogma
Only dealing with this part today!
DNA
mRNA
Protein
Translation
Transcription
Nucleus
Ribosome

5. Makes body structures- Muscles, bones, etc
Makes body structures- Muscles, bones, etc. Enzymes Used to transport large molecules across the cell membrane

6. Transcription Transferring information from one form to another
Speaking To
Writing
Same information, different form

7. English to Spanish

8. DNA mRNA Same information but a different form
first step in making a protein (polypeptide)
occurs in the nucleus

9. Messenger RNA (mRNA): carries instructions from DNA to the rest of the cell

10. Ribonucleic Acid What is RNA?
Analyze this RNA structure Talk with your partner and decide how this is different than DNA

11. U T DNA & RNA Differences: 1) RNA has ribose instead of deoxyribose
2) RNA is single stranded
3) RNA has uracil instead of thymine U T

12. DNA-Instructions for EVERYTHING

13. RNA – Partial Instructions

17. Copy this into your notes!!
DNA to DNA
DNA to RNA
C  G
G  C
T  A
A  T
C  G G  C T  A A  U

18. What’s the point?
genetic information (DNA) is turned into a Protein DNA is just the information, our useful product is our protein

19. Transcription Recap (big ideas)
Is the first step in making a protein (polypeptide)
Occurs in the nucleus
DNA is used to make RNA
RNA has U instead of T
RNA is then sent out into the cell to make proteins
It’s usually just a section of the DNA strand (gene) that codes for one specific protein
