Chapter 12 DNA: The Genetic Material Review
  1. The physical structure of DNA is a sequence of monomers called nucleotides which form a double .
     
     
     
  2. DNA involves these steps:
     
     
     
    • The enzyme unwinds the double helix, and lays down an RNA .
       
       
       
    • DNA adds nucleotides to each strand.
       
       
       
    • DNA joins the fragments together.
     
     
     
    Summary:
     
     
     
  3. A is a change in the DNA sequence that may affect proteins.
     
     
     
  4. Some genes can "jump" from one place on the chromosome to another through a process called and result in a mutation.
