Codons are used for making amino acids. Some codons will tell the ribosomes to start tell the tRNA to make the amino acids or to stop making amino acids. I like to think of the start/initiator/promoter codon(AUG) as a capital letter in a sentence and the stop/terminator codons(UAA, UAG, and UGA) as periods in a sentence.

How is a DNA sequence translated into a protein?
During the process of protein synthesis, a DNA sequence is first transcribed into messenger RNA (mRNA) by RNA polymerase. The mRNA then moves to a ribosome, where transfer RNA (tRNA) molecules bring specific amino acids to the ribosome based on the mRNA codons. The ribosome reads the mRNA codons in groups of three (codons), and matches them with the corresponding tRNA anticodons, which carry the specific amino acids. This process continues until a stop codon is reached, signaling the end of protein synthesis and the release of the newly formed protein.
Which mRNA condon usually signals the beginning of protein synthesis?
Methionine is always the first amino acid in a protein, therefore the codon for Met would signal the beginning of protein synthesis. This codon is AUG.
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.
What is the first step in protein synythesis?
The first step of protein synthesis is transcription, where the DNA "unzips" to direct the production of a strand of messenger RNA (mRNA). This carries the instructions for the production of protein to the ribosome. Transcription is further divided into three stages: into 3 stages: initiation, elongation, and termination.
The amino acid that initiates protein synthesis?
The amino acid that initiates protein synthesis is methionine. It serves as the starting point for the translation process, providing the first building block for the growing polypeptide chain.
What do codons UGG and AUG have in common?
AUG is the only codon which codes for methionine and UGG is the only amino acid that codes for Tryptophan. These are the only codons which have only one codon to represent their specific amino acid.

What happeneds in synthesis?
First, the DNA polymerase makes a copy of the DNA. The nucleotides then bond together and form a complete mRNA strand. The mRNA strand travels out to the cytoplasm through the nucleus. The mRNA is then met by a ribosome and tRNA. Codons and amino acids are then created. After the tRNA detaches from the mRNA strand, the amino acids are connected by a polypeptide bond. This results in a protein. So basically... Protein synthesis is going from DNA to mRNA to tRNA to a protein.
Which mRNA condon usually signals the beginning of protein synthesis?
Methionine is always the first amino acid in a protein, therefore the codon for Met would signal the beginning of protein synthesis. This codon is AUG.
Where is the first step of protein synthesis occur?
on the ribosomes in the cytoplasm of the cell
What do you mean by stop codons?
a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation.Three codons UAG,UAA & UGA are the stop codons, which denotes the end of the protien.
Why is accurate initiation of protein synthesis important?
It is the first step in creating proteins.
What amino acid is usually the first one inserted into a protein during protein synthesis?
A protein is a topic that is vital, and that requires professional tending to regarding

What is the significance of the AUG start codon in relation to methionine in the process of protein synthesis?
The AUG start codon is significant in protein synthesis because it signals the beginning of protein formation. It codes for the amino acid methionine, which is often the first amino acid in a protein chain. This helps initiate the process of building a protein molecule.
