5 Questions
What is the genetic material of all organisms?
Nucleic acid, specifically deoxyribonucleic acid (DNA) in the majority of organisms.
How can DNA be cut with restriction enzymes?
The DNA needs to be in pure form, free from other macro-molecules, and the cell needs to be broken open to release the DNA along with other macromolecules.
What enzymes are used to break bacterial cells, plant cells, and animal tissues to release DNA?
Lysozyme for bacteria, cellulase for plant cells, and chitinase for fungus.
What proteins are DNA interwined with?
DNA is interwined with proteins such as histones.
How is purified DNA obtained after breaking open the cell and releasing DNA along with other macromolecules?
Purified DNA ultimately precipitates out after the addition of chilled ethanol.
