How does the point mutation that you made change the DNA code on your molecule? (2pts) B. Referring to your textbook, explain how mutations can occur in cells and how such changes might affect an organism with the mutation. (2pts)

Although DNA and RNA synthesis have many shared features, there is a distinctive property in RNA synthesis which is absent in DNA. Which of the following is this?

Although DNA and RNA synthesis have many shared features, there is a distinctive property in RNA synthesis which is absent in DNA. Which of the following is this? a. 5' to 3' direction of synthesis b. RNA polymerase can begin synthesis of a new RNA strand by first adding nucleoside triphosphate; DNA polymerase requires a primer sequence c. New strands are produced by using existing strands as a template d. Synthesis requires nucleoside triphosphates as a cellular supply
