Reviewing Reading a Codon Chart

If the DNA sequence of a gene is TAC GCA AAA TAT, what mRNA sequence will be produced in transcription?

• RNA Polymerase

• AUG CGU UUU AUA

• ATG CGT TTT ATA

• UAC GCA AAA UAU

• AUG CCG UUU AUA

If the DNA sequence of a gene is CAT TAC CCC GGG, what mRNA sequence will be produced in transcription?

• nucleus

• AUG GGG CCU CUC

• GUA AUG GGG CCC

• GUA AUG CCC GGG

• CAU UAC CCC GGG

What amino acid would be added to the protein being formed during translation if the mRNA codon reads "AUG?"

• Phenylalanine

• Tyrosine

• Leucine

• Methionine

What amino acid would be added to the protein being formed during translation if the mRNA codon reads "CCU?"

• Proline

• Tyrosine

• Leucine

• Serine

What amino acid would be added to the protein being formed during translation if the mRNA codon reads "CCG?"

• Isoleucine

• Stop

• Methionine

• Proline

What is the correct amino acid sequence for the mRNA code AUG GCA UGA CGU

• Met-Ala-Asn-Ala

• Met-Ala (because the third codon codes for STOP)

• Ileu-Ala-Asn-Ala

• Met-Ala-Asn-Arg

• Ileu-Ala-Asn-Ala

What is the correct amino acid sequence if the DNA code of the gene is TAC AGA TTT CAC?

*You will have to figure out the mRNA codons before figuring out the amino acid sequence

• Met-Ala-Lys-Ala

• Met-Ser (because the third codon codes for STOP)

• Ileu-Ala-Asn-Ala

• Met-Ser-Lys-His

• Met-Ser-Lys-Val
