Which of the following is not true about the codon code?
A
One sequence (AUG) initiates translation
B
The number of codons is more than the number of amino acids
C
Out of three possibilities there is only one correct start site (frame) for each gene
D
Anticodons are encoded in the DNA of the gene
Verified step by step guidance1
Understand that codons are sequences of three nucleotides in mRNA that specify which amino acid will be added next during protein synthesis.
Recognize that AUG is the start codon, which initiates translation and codes for the amino acid methionine.
Acknowledge that there are 64 possible codons (4^3 combinations of the four nucleotides), but only 20 amino acids, meaning multiple codons can code for the same amino acid.
Realize that the reading frame is crucial in translation, and there is only one correct start site for each gene to ensure the correct protein is synthesized.
Clarify that anticodons are not encoded in the DNA; they are part of tRNA molecules that pair with the mRNA codons during translation.
