Title: An E. coli strain contains a mutation in the malate dehydrogenase gene that results in a stop codon ... Post by: Hems271 on Feb 3, 2018 An E. coli strain contains a mutation in the malate dehydrogenase gene that results in a stop codon at amino acid position 14.
From subcultures of this strain, a colony was obtained that was capable of making malate dehydrogenase. Your approach to examining this phenomenon should be to examine A) the DNA sequence to see if a reversion has occurred. B) the DNA sequence to see if a suppressor mutation has occurred. C) other proteins to see if other stop codons are ignored, indicating the presence of a suppressor tRNA. D) the DNA and plasmids for the incorporation of a second complete copy of the malate dehydrogenase gene. E) All of these approaches need to be considered.
