The mRNA start codon, usually AUG, plays a crucial role in initiating protein synthesis. It signals the ribosome to start translating the mRNA sequence into a protein. This codon marks the beginning of the protein coding sequence and helps establish the correct reading frame for translation.

What is the significance of the AUG codon in the process of protein synthesis?
The AUG codon serves as the start codon in protein synthesis, signaling the beginning of translation. It codes for the amino acid methionine, which is often the first amino acid in a protein chain. This codon is crucial for initiating the assembly of proteins in cells.
What is the significance of the sequence "ATG" in DNA and how does it relate to the process of protein synthesis?
The sequence "ATG" in DNA serves as a start codon, indicating the beginning of protein synthesis. This sequence signals the cell to start translating the genetic information into a protein. It is crucial for initiating the process of protein synthesis and ensuring that the correct protein is produced.
What codon is typically used as the start codon in protein synthesis?
The codon typically used as the start codon in protein synthesis is AUG.
What are the start and stop codons that are essential for initiating and terminating protein synthesis?
The start codon that initiates protein synthesis is AUG, which codes for the amino acid methionine. The stop codons that terminate protein synthesis are UAA, UAG, and UGA.
Why is AUG the start codon in genetic translation?
The AUG codon serves as the start codon in genetic translation because it codes for the amino acid methionine, which is essential for initiating protein synthesis. This codon signals the ribosome to begin translating the mRNA sequence into a protein.

What is the significance of the tryptophan codon in genetic coding and how does it affect protein synthesis?
The tryptophan codon is important in genetic coding because it signals the incorporation of the amino acid tryptophan into a protein during protein synthesis. This codon acts as a specific instruction for the cell's machinery to add tryptophan to the growing protein chain. If there is a mutation in the tryptophan codon, it can lead to errors in protein synthesis, potentially affecting the structure and function of the resulting protein.
What is the start codon for mRNA?
The start codon for mRNA is AUG, which codes for the amino acid methionine. It signals the ribosome to start translation and is crucial for initiating protein synthesis.
What is the significance of the ATG start codon in the process of protein synthesis?
The ATG start codon is significant in protein synthesis because it signals the beginning of protein translation. It serves as the start signal for the ribosome to begin assembling the amino acids into a protein chain. Without the ATG start codon, the ribosome would not know where to begin protein synthesis, leading to errors in the process.
What codon initiates protein synthesis?
The codon that initiates protein synthesis is AUG, which codes for the amino acid methionine.
What is the significance of the start codon AUG in the process of protein synthesis?
The start codon AUG is significant in protein synthesis because it signals the beginning of protein translation. It initiates the assembly of amino acids into a protein chain, serving as the starting point for the ribosome to begin reading the mRNA and synthesizing the protein.
What role does the codon play in initiating protein synthesis?
The codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid. During protein synthesis, the codon acts as a signal to start the process of translating the genetic code into a protein. It initiates the binding of the appropriate transfer RNA (tRNA) molecule carrying the corresponding amino acid to the ribosome, where the amino acids are linked together to form a protein.
What codon serves as the start codon for protein synthesis?
AUGMethionine is specified by the codon AUG, which is also known as the start codon. Consequently, methionine is the first amino acid to dock in the ribosome during the synthesis of proteins.
