  • 33. This process is very important. It is what allows for DNA to be copied. Also, it allows for certain parts of DNA to be copied (when the body needs to make more of a certain thing.) Also, when cells copy, it allows for the copied cell to have the same DNA and to allow it to perform the same function.
  • 34. One problem is that genetic mutations can occur. This is when the bases pair up with a non-corresponding base. For example, when A-G pair up and when CT pair up. Some example of genetic mutations are most types of cancer, Sickle-Cell Anemia, and Down Syndrome.
