Answer:
AUG
Step-by-step explanation:
The sequence "AUG" is the start codon for translation and is also known as the initiation codon. It is a consensus sequence, meaning that it is the most commonly observed sequence at the beginning of protein-coding genes in prokaryotic mRNAs. When an AUG codon is encountered by the ribosome, it signals the start of protein synthesis and the ribosome begins to translate the mRNA sequence into a protein sequence. The start codon is recognized by a specific initiator tRNA molecule that carries the amino acid methionine, which is the first amino acid in many proteins.
