Question

The signal to start translation is the initiator codon, usually AUG, the codon for: a. Tyrosine b. leucine c. methionine d. initiator proteins
Options
A Tyrosine
B leucine
C methionine
Correct Answer
D initiator proteins
Correct Answer

Option C is the correct answer.

Detailed Explanation

The codon AUG serves two functions: it codes for the amino acid methionine and it acts as the 'start' signal for translation in eukaryotes (in bacteria, it codes for a modified methionine, fMet).

Hint

This amino acid is also the one that starts nearly all protein synthesis.
