Transcript
Name: _____________________Class: ______ Date: _________________________ BELL RINGER Information, Please Genes in cells are made of DNA, which is a complex molecule. The structure of a DNA molecule contains the information that a cell needs to carry out all of its functions. In a way, DNA is like the cell’s encyclopedia. Suppose that you go to the library to do research for a science project. You find the information you need in an encyclopedia. You go to the desk to sign out the book, but the librarian informs you that this book is for reference only and may not be taken out. 1. Why do you think the library holds some books for reference only? Why do you think that cells keep DNA in their nuclei? 2. If you can’t borrow a book, how might you take home the information in it? How do you think this method may be similar to processes that occur in cells? 3. All of the parts of a cell are controlled by the information in DNA, yet DNA does not leave the nucleus. How do you think the information in DNA might get from the nucleus to the rest of the cell? 4. What might happen to a cell if its DNA was to be damaged?
