For disease class, we went to the DNA lab in the Field Museum. We learned that DNA mutations can cause a disease. Also, we had the opportunity to interview a scientist.

Every student had questions for the scientist and I asked the following questions:

How does DNA change over generations? And why?
Genetic mutations is the thing that can change but your’re most likely to have the same DNA as your family line. Genetic mutations can cause diseases and that depends on how your old generations lived. Our DNA has a history of changes that happened in our past and may continue to happen. All of these DNA changes happens randomly.

Where does DNA from?
DNA comes from your parents and previous generations.

3. How does DNA form?
DNA forms when your cells are building up. Chromosomes contain DNA-bound proteins, which serve to package the DNA and control its functions. The essential unit of DNA packaging is the nucleosome. A nucleosome consists of a small amount of DNA wrapped up with protein. The proteins that interact with DNA to form chromatin comprise a family of basic proteins called histones. Histones is a basic proteins most commonly found in association with the DNA in the chromatin of eukaryotes.
