What is the correct amino acid sequence for the mRNA code AUG GCA AAC 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 CGT TTG GCA?

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

• 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
