RNA Polymerase
AUG GGG CCU CUC
ATG GGG GGT GTG
AUG GGG CCU CUG
AUG CCG GCA CGG
If the DNA sequence of a gene is GAC CAA TAT GTA, what mRNA sequence will be produced in transcription?
nucleus
AUG GGG CCU CUC
CUG GUU AUA CAU
GAC CAA UAU GUA
CUG CCG GCA CGG
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?"
Isoleucine
Stop
Methionine
Proline
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
