Module 6A homework

10 points

Who did the density gradient experiment to show DNA replication is semi-conservative? __ (1 pt)

How did they label their DNA? (that means, how did they make 2 types of DNA that were different? __(1 pt)

What was the density gradient they used made of ? __ (1 pt)

On the next slides, I have turned the density gradient tube upright. In the textbook images, it is horizontal. Each page asks you to indicate where DNA will land after centrifugation.

These are the control tubes. 1. Label them appropriately a light or heavy 2. Use color bands to show where a mix of light and heavy will go. (2 points on this slide) (Hint: to change color of an object, right click it, then select the color in the bucket icon)

Mix of heavy and light

These are the control tubes. 1. Copy your mix of heavy and light into this slide 2. Draw in the results of the first generation 3. Draw in the results of the 2nd and 3rd generations. Verify this with your notes. (3 points)

Mix of heavy and light

1st generation 2nd generation 3rd generation

How do these results demonstrate semiconservative replication?(1 pt)

How do these results disprove conservative replication?(1 pt)
