What does rRNA do?
rRNA reads the DNA and creates mRNA
rRNA reads the order of amino acids and links them together.
rRNA does not exist.
rRNA carries anticodons for the DNA.
What does a silent mutation do?
It doesn't affect the sequence of amino acids at all.
It will always cause a fatal mutation. (The silent killer)
It will change amino acids and get rid of stop codons.
It will insert base pairs.
What are the different types of Substitution Mutations?
Silent Mutations
Missence Mutations
Nonsense Mutations
Frameshift Mutations
(insertion and deletion)
Complementary Mutations
What's a codon?
It's the thing that unzips DNA
It's just another word for DNA
Sets of two bases on the tRNA strand.
Sets of three bases on the mRNA strand.
What does a Missense Mutation do?
Changes the order of Start and Stop codons.
Doesn't affect anything.
Changes the genetic code so that the amino acid is different than it normally would be.
Changes the genetic code so that extra stop codons are put in.
RNA is single stranded.
FALSE
TRUE
Where does Transcription take place?
Cytoplasm
Mitochondria
Nucleus
Cell Membrane
What does RNA polymerase do?
RNA polymerase copies the DNA sequence into a RNA sequence.
RNA polymerase "unzips" the DNA.
RNA polymerase creates ribosomes to read mRNA
RNA polymerase creates a whole other double helix.
What does the ribosome do in protein synthesis?
The ribosome acts as a protective barrier for protein synthesis.
The ribosome translates the genetic code from the mRNA into an amino acid sequence.
The ribosome makes sure the correct amino acids are becoming the correct amino acid chains.
The ribosome trransports the mRNA from the nucleus into the cytoplasm.
The ribosome takes the genetic code and destroys it before amino acids can be made.
What does an anti-codon do?
An anti-codon is attached to mRNA and pairs with the DNA sequence to make sure the genetic information is correct.
An anti-codon is attached to tRNA and will pair with it's complementary codon on the mRNA molecule, making sure the right amino acid is put into amino acid chain.
An anti-codon is a molecule that leaves the nucleus and travels through the cytoplasm.
What does tRNA do?
tRNA transfers the amino acids coded by mRNA
tRNA transfers the RNA out of the nucleus.
tRNA acts as a link between the mRNA and the growing protein chain.
tRNA reads DNA
What does a Frameshift Mutation do?
Removes half the base pairs in the genetic code.
Adds or removes base pairs into the genetic code.
Inserts and takes away stop and start codons in the DNA.
Insets random amino acids into the chain of proteins.
What are the five bases of DNA and RNA?

Uracil (RNA)
Guanine

What does DNA Helicase do?
DNA Helicase copies the DNA.
DNA Helicase "unzips" the DNA
DNA Helicase reads the genetic info on the DNA.
DNA Helicase separates the two strands of the double helix of DNA.
What does a nonsense mutation do?
Rearranges the genetic code so that the amino acids don't form correctly.
Adds a stop codon in too late.
Adds in a stop codon too early so the sequence ends early.
Inserts extra codons.
What is the start codon?
ACC
AUG
GUU
ATC
What are the three stop codons?
There are no stop codons it goes on forever.
UAA, UAG, UGA
AUG, ATT, CUG
GUA, ACC, GGG
What is a nuclear pore?
Where codons are made.
Where the RNA exits the Nucleus.
Where the DNA exits the Nucleus.
The nucleus sweats.
Where does Translation take place?
Ribosomes
Nucleus
Cytoplasm
Red Blood Cell
What does mRNA do?
mRNA carries the code for a protein from DNA (moves from the nucleus to the cytoplasm).
mRNA carries the anti-codons for creating proteins.
mRNA reads the anti-codons
DNA is double stranded.
TRUE
FALSE
What is the process called when RNA changes into protein?
Translation
DNA Helicase
rRNA
Transcription
What process is it when DNA changes into RNA?
Polypeptide Bonding
Transcription
Protein Synthesis
Translation
