Without the presence of start codons, Protein synthesis would not occur. Option B is correct.
In the synthesis of proteins, codons are referred to as the genetic codes that represent each of the amino acids that form the protein. These codes are in groups of three base nucleotides. The mRNA or messenger is the carrier of the code that will be responsible for the production of a certain protein.
A start codon is a three-base pair of nucleotides that holds the code needed to initiate the protein synthesis. The most common start codon in humans is AUG. Without the start codons, mRNA would still be taken to the ribosomes for protein synthesis but the process would not be able to begin.
