Multiple Choice
In the context of the central dogma, what amino acid is specified by the mRNA codon AUG during translation?
A
Leucine (Leu)
B
Valine (Val)
C
Tryptophan (Trp)
D
Methionine (Met)
Verified step by step guidance1
Understand that the central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein.
Recall that during translation, mRNA codons are read in sets of three nucleotides, each specifying a particular amino acid.
Identify the mRNA codon given in the problem: AUG.
Use the genetic code table to find which amino acid corresponds to the codon AUG.
Recognize that AUG is the start codon and codes for the amino acid Methionine (Met).
