Interactive Class Notes / Learning Log / Textbook Notes Learning Goal(s):  o SC.912.L.16.3:  Describe the basic process of DNA replication and how it relates to the transmission  and conservation of the genetic information.  Think About It The DNA molecule must somehow specify how to assemble proteins, which are needed to regulate the various functions of each cell. What kind of structure could serve this purpose without varying from cell to cell? Understanding the structure of DNA has been the key to understanding how genes work. Also consider, before a cell divides, its DNA must first be copied. How might the double-helix structure of DNA make that possible?       Intro:   The Secret of Life: Discovery of DNA Structure Remember to  REVIEW  these  notes daily so you will be ready  to participate in class discussion the next day.  This practice of  daily review will also prepare  you for future assessments.

Questions/Main Ideas:                                               Notes: & Key Terms In My Own Words (“How will I remember each term?”) Include Images and Hyperlinks Make it Personal 1. Have you heard of the  word DNA before? If  so, when was the first  time you heard the  word DNA mentioned? 2. Estimate how much  DNA is in your body… then remove the black  highlight to find our. 1. Answer: yes, in elementary school in science. 2. enough dna to fill the earth. Key Questions What are the chemical components of DNA? Nucleic acid made of nucleotides joined into strands or chains by covalent  bonds What clues helped  scientists solve the  structure of DNA? The clues in franklins X-ray pattern enabled Watson and crick to build a  model that explained the specific structures and properties of DNA  What does the double- helix model tell us  about DNA? The double helix model explains Chargaff’s rule of base pairing and how the  two strands of DNA are held together  Key Vocabulary Make Sure That  YOU  are using  YOUR OWN  words.   DON’T COPY  and PASTE  Definitions.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
