DNA Lab 5.18.12
-DNA is the molecule of life
-it is the heredity material found in every cell that provides instructions for making proteins
-proteins are responsible for most of the structure of cells and are involved with controlling chemical reactions as enzymes
-Prokaryotic cells have DNA floating in the cytoplasm, whereas eukaryotic cells have nuclei that contain DNA (in the nucleus)
1. Describe the appearance of the split green pea DNA.
The DNA were coming up in white strands.
2. Describe the appearance of your cheek DNA.
Though it is faint, you can still see the strands of DNA rising up from the mixture.
3. Does the appearance of DNA differ between organisms?
No, the DNA were in both cases, strands.
4. How do you think scientists tell the difference between the DNA of different organisms?
They look it up under a microscope, and can tell by the location of the DNA.
5. What was the purpose of adding detergent to the cell mixture?
Detergent breaks open the cell membrane and nuclear membrane by destroying the lipid bilayer that surrounds the cell and nucleus.
