Transcript 64 DNA to RNA

Bellwork Tues 1/3/12
*New semester means clean slate. Grades, tardies, etc.
1. What is one thing you want to focus
on in this class to make sure you
get a good grade this semester?
What will you do specifically?
*2 sentences
Agenda:
1. Class feedback
2. DNA review
3. RNA take your own notes
The heck is that thing? 
SEATS! 2ND HOUR
SEATS! 3RD HOUR
SEATS! 5th HOUR
SEATS! 6th HOUR
SEATS! 7th HOUR
Class feedback
Common Dislikes
• Assigned seats
• Notes
• Desk arrangement
• Not being able to eat food
Common Likes
• Labs
• Using notes on tests
• Choosing lab groups
• Not much homework
DNA Review
Whiteboard reminders:
• Please only write answers to the questions
• Make sure paper towels get into the trash
• All group members should contribute
Whiteboard questions
1.
2.
3.
4.
5.
What were those three parts of DNA?
What were the 4 bases in DNA?
What is the name of the shape of DNA?
Draw DNA, and label as much as you can
What is the complementary strand to:
ACCTAGTTAK
6. Draw the steps of DNA replication (there are
three main steps)
7. What is DNA made into? E.g. what comes
after DNA? (We have not covered this yet)
DNA models Review
RNA vs DNA Take your own notes (p. 294 – 297)
*Answers to some questions might overlap
*To help you understand the answers, write them in your own words rather than copying
*You can use these notes on the test so the more you write the better
1. What does your body use the information in DNA for?
2. What does your body use proteins for?
3. What is RNA and how is it similar to DNA? What are
some differences? (might overlap with later questions)
4. What is the role of RNA in the cell?
5. Which bases is RNA made of?
6. Which bases match together in RNA?
7. Where in the cell is DNA found, and where is RNA
found
8. How many strands in RNA?
9. What are the 3 types of RNA and what does each do?
10. Draw a picture to represent the job of each of the 3
types of RNA do (Can be a metaphor, such as a
picture of a worker)
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)
rRNA
mRNA
tRNA
• RNA is complementary to DNA
– DNA:
– mRNA:
C A T G T A G C T
_ _ _ _ _ _ _ _ _
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.
