Answer these questions in your notebook and then take a photo and add it here.

DNA and RNA Structure

1. How is genetic information stored in living organisms?

2.  Genetic information is passed from parent to daughter cells by __________ which is packaged into __________________

3.  What molecule can some viruses use to encode genetic information?

4.  Describe three similarities between DNA and RNA.

5.  What are the base pairing rules for DNA?  How are the base pairing rules for RNA different?

6.  What is the major structural difference between purines and pyrimidines?

7.  How are prokaryotic and eukaryotic genomes different?  (Give at least three differences)

REMEMBER: Watch the video all the way to the end so that AP Classroom gives your credit for watching the video

Replication

1.  What is the purpose of DNA replication?

2.  What does “semiconservative” replication mean?

3.  How is the 5’ terminus different from the 3’ terminus of DNA?

4.  What does antiparallel mean?

5.  Because new nucleotides can only be added in the 5’ to 3’ direction, one strand is called the leading strand and is synthesized ______________________ and the other strand is called the lagging strand and is synthesized __________________________________

6.  Describe the function of each of the following enzymes in DNA replication:
Helicase

Topoisomerase

DNA polymerase

Ligase

7.  How are the functions of helicase and topoisomerase related?

Include a screenshot here of the DNA you built and a screenshot of what happened when you added the Enzyme DNA Polymerase.

Complete the GIZMOS Activity A found in Google Classroom and turn it in.

Must have:
* Title:  DNA Replication Cartoon
* 4 quadrants
* at least 3 colors

- What is DNA Replication?
- Bases (Names and Shapes)
- DNA (Label Sugar, Phosphate, Bases and 3' & 5' ends)
- Enzymes and what they do (Include unique drawings/cartoons showing what they do)
- include:  Helicase, Ligase, Primase & DNA Polymerase

When you are done, did everyone write their name on the part they were responsible for?  Now, in order, share your section with your team.  Be prepared to present your poster to another team on Friday.

If your team needs more time, please arrange to come in at lunch, or take your poster home and then return it on Friday.  But, if you take your poster, it must be in class on Friday so you team is not penalized.
