1. The name of the kind of molecule that breaks DNA at specific points is... rRNA?
2. A group of three base pairs in DNA is a code for a specific amino acid or is it a specific protein?
3. Which result in the greatest change in the protein produced:
a. substituting one base pair for another base pair in a DNA molecule
b. adding three base pairs into a DNA molecule
c. adding one base pair the beginning of the DNA molecule
^ Which one is it and why?
4. What is the significance of the type of bond which holds the base pairs together?
a. They are strong, and that allows the 2 halves of the molecule to separate and replicate
b. They are strong, and that allows the DNA to move to the ribosome
c. They are weak, and that allows the 2 halves of the molecule to separate and replicate
d. They are weak, and that allows the DNA to undergo mutation whenever it replicates
