DNA
What is the shape of DNA called?
Double Helix
Every three bases on mRNA is called a _________.
Codon
Earthworms use the same genetic code as humans.
What does DNA stand for?
Deoxyribonucleic Acid
If the mRNA codon is UAG, then what is its complimentary tRNA anticodon?
AUC
Proteins are made up of long chains of __________.
Amino acids called Polypetides
If the tRNA anticodon is CGC, then what is the amino acid?
Ala; Alanine
What enzyme breaks apart the hydrogen bonds between two strands of DNA?
Helicase
What is the bond called that holds two nitrogenous base pairs together?
Weak Hydrogen Bonds
What are the steps to DNA Transcription?
Attach, Start, Slide, Stop
If a frameshift mutation from exposure to radiation caused a segment of RNA to change from AUC to UAG, what would happen to the protein during translation?
It would stop
Where does translation take place?
Within the cytosol; In the cytoplasm at a ribosome
What is the genetic code?
Allows us to decode mRNA to Amino Acids
What is the process called where DNA makes an exact copy of itself?
DNA Replication
What is the name of the enzyme responsible for creating mRNA and what is that process called?
RNA polymerase, transcription
What amino acid would pair up with the beginning DNA bases TAC? and Why is it important?
Methionine
Is mRNA or tRNA used to code for an amino acid and why?
mRNA because it is made from DNA and carried the original genetic information that the ribosome will use to make protein. tRNA just delivers the building blocks

If 30% of a specific DNA sequence are “G”, what percentage will be “A”?
20% of Adenine
What enzyme function is needed for RNA polymerase to start its job?
Nothing, RNA polymerase both unwinds and recruits nucleotides for mRNA
Name the steps to DNA Translation?
Attach, Start, Slide, Stop
What is the Central Dogma?
DNA Replication to DNA Transcription to RNA Translation
