Detailed explanation-1: -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.
Detailed explanation-2: -Answer and Explanation: No, translation will not start until the ribosome reaches a start codon. That said, the start codon is simply a codon that codes for Methionine. Because of this if the amino acid chain was supposed to start with Met-Met the second Methionine would start the translation.
Detailed explanation-3: -Errors in protein synthesis disrupt cellular fitness, cause disease phenotypes, and shape gene and genome evolution.
Detailed explanation-4: -Start codons are important to understand because they mark the beginning of a recipe for translating RNA into specific strings of amino acids (i.e., proteins).
Detailed explanation-5: -The start codon marks the site at which translation into protein sequence begins, and the stop codon marks the site at which translation ends.
