The position of the start codon is important because every molecule of mRNA can be read by a ribosome in three different ways.

Question

Quizplus · Accepted Answer

The start codon (AUG) is the first codon in the mRNA sequence, indicating the beginning of the coding region. The ribosome reads the mRNA sequence in three nucleotide units (codons) and starts translating protein from the codon that matches the start codon. Therefore, the position of the start codon is crucial for determining the correct reading frame and eventual protein synthesis.
