Which enzyme matches the complementary base pairs in DNA replication?
DNA Polymerase
What are the two steps of protein synthesis?
Transcription and Translation
True or False. The insertion of a nucleotide into DNA would cause a mutation.
True.
What are the three parts of a nucleotide that makes up DNA?
phosphate group, deoxyribose sugar, nitrogenous base
What are the three parts of a nucleotide that makes up RNA?
phosphate group, ribose sugar, nitrogenous base
What is the outcome of DNA replication? Describe what is made. (how many DNA molecules, how many new strands, how many original strands).
Two DNA molecules, each has one original strand and one new strand.
Which type of RNA carries amino acids to the site of protein synthesis?
tRNA
True or False. Mutations can only be inherited if they occur in the sperm in sexually reproducing organisms?
False. Sperm and Egg!

What is the process of DNA to RNA called?
Transcription
Have your group get up and demonstrate DNA replication. One person is DNA helicase, one person is DNA polymerase, Two people are A, Two people are T. Go!
What is it called when RNA is made into proteins?
Translation
What are the three types of mutations?
Substitution, Deletion, Insertion
