Question	Answer
When cells grow & develop by synthesizing (making) the proteins that give organisms their traits and characteristics from DNA & RNA	Protein Synthesis
When DNA is replicated, so when the cell divides each new cell doesn’t end up with only half the required amount of DNA.	DNA Replication
Newly replicated DNA is checked for errors before the cell divides	Checkpoint
What is instructional genetic code for making the proteins that give living things their traits & characteristics.	Deoxyribonucleic Acid
What is single stranded; uses DNA’s instructions to make proteins	Ribonucleic Acid
What involves growth, development and division	Cell Life cycle
What is the cell growth & development phase before division	Interphase
Hydrogen Bonds connect the nitrogen bases Cytosine to Guanine (“CG”) and Adenine to Thymine (“AT”) in DNA to form double helix or Adenine to Uracil (“AU”) in RNA	Base pairings
Each strand of double helix DNA	Sugar Phosphate Backbones

Traits are expressed by ________	Proteins
Enzyme _______ catalyze (speed up) chemical rxns	Proteins
Each protein has a unique shape and function because they have a unique number and sequence of different amino acid building blocks. When we learned about enzyme proteins, we also learned that when proteins lose their unique shape, they also lose their unique function.	Amino Acids
Cytosine, Guanine, Adenine, Thymine in DNA or Uracil in RNA	Nitrogen Base
