DNA REVIEW GAME

Exam on Monday 11/24!

RulesO Your group will get one whiteboard and dry erase

marker. O I will show the question on the screen and read it

aloud. O Your team will have 20 seconds to write down the

correct answer. O When I tell you to, hold up your white board. O Teams with the correct answer will receive a point. O Important – I will be randomly calling on

someone in class to explain how the group reached the correct answer so be prepared!

Remember….O Keep the noise volume down – you

do not want another group to hear your answers!

O Make sure you talk about your answer with the group so everyone understands!

LET’S PLAY

about DNA?

Answer 5O DNA is the stuff in our cells that

stores and transmits genetic information from one generation to the next

Question 6O Erwin Chargaff made what discovery

about DNA?

Answer 6O DNA is made of four nitrogen bases.

Adenine (A) always pairs with Thymine (T) and Cytosine (C) always pairs with Guanine (G)

Questions 7O What work did Rosalind Franklin do

to advance our knowledge about DNA?

Answer 7O She took an x-ray of DNA to help

figure out its shape

Crick tell us about the shape of DNA?
