Question

The initiator codon, AUG codes for which of the following amino acids?

• A. Methionine
• B. Leucine
• C. Arginine
• D. Glycine

Hint:

Remember the mnemonic "AUG starts the engine with Met" (Methionine).

Answer 1

The Correct Option is A

Step 1: AUG is known as the start codon or initiator codon because it marks the site where translation (protein synthesis) begins.
Step 2: In eukaryotes, AUG always codes for the amino acid Methionine.
Step 3: It has a dual function: it codes for an amino acid and also acts as the "start" signal for the ribosome.
