Where does Transcription and Translation take place and what are the end products of each?

• Transcription takes place in the nucleus and produces mRNA;

  Translation takes place in the ribosome/cytoplasm and creates a protein (polypeptide)

• Transcription takes place in the ribosome and produces protein (polypeptide);

  Translation takes place in the nucleus and creates mRNA

• Transcription takes place in the nucleus and produces protein;

Transcribe the DNA into mRNA then Translate the mRNA into protein using the codon chart

CAC GTA ATT

• GUG CAU UAA

  VAL HIS STOP

• GUC CGU UAA

  VAL ARG GLU

  START ARG STOP

What are the correct functions of each type of RNA?

• mRNA-Encodes genetic information from DNA during transcription

  tRNA-Carries amino acids to ribosomes during translation

  rRNA-Helps build the ribosomes that are used in translation

• mRNA-Helps build the ribosomes that are used in translation

  tRNA-Encodes genetic information from DNA during transcription

  rRNA-Carries amino acids to ribosomes during translation

• mRNA-Carries amino acids to ribosomes during translation

  tRNA-Helps build the ribosomes that are used in translation

  rRNA-Encodes genetic information from DNA during transcription

What is the complementary RNA codon for the DNA codon CAG

• GUC

• GTC

• CAG

• CTG

The following diagram shows-

• The translation of mRNA into a protein

• The transcription of a gene to be used in making proteins

• DNA being replicated

.

Why are insertion and deletion (frameshift) mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• Insertion and deletions are not any more harmful than substitution mutations.

Which type of RNA carries the amino acids to the ribosome?

• mRNA

• tRNA

• rRNA

• RNA polymerase

Put the steps of protein synthesis in the correct order.

answer choices

• I, II, III, IV

• II, III, I, IV

• IV, II, I, III

• IV, III, II, I

The diagram shows which process?

• Create a mRNA

• Copy original DNA strands into complementary strands

• DNA being replicated

• Create protein (polypeptides) for gene expression

What is the function of mRNA?

• Brings together tRNA and rRNA

• Carries the instructions (message) from DNA to the ribosome

• Carries the amino acids to build proteins
