Protein Synthesis Test Study Guide + Bonus Mutation Questions!

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.
