What meaning do the first and last codons have for protein synthesis?
Wiki User
∙ 9y ago
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.

∙ 9y agoA codon is a three nucleotide sequence that codes for a specific amino acid. Codons are read from the mRNA to produce amino acid chains.

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.
In eukaryotic cells the first step in protein synthesis is the?
transferring of information from DNA to messenger RNA
What is the degradation and synthesis of protein called?
denaturation for degradation synthesis: first step is Transcription, The second step is Translation; there are additional steps (post-translational modifications) after that the polypeptide is formed including the formation of 3D conformation
3 steps of protein synthesis?
In the body, proteins are synthesized inside organelles known as ribosomes. The first step in protein synthesis is the transcription of mRNA from a gene of DNA. The second step is for protein synthesis to begin and the formation of a protein chain to take place. The third step is for the ribosome to terminate production of the protein, hydrolyze the ingredients that initiated protein production, and then release the protein from the ribosome.
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 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.
Where is the first step of protein synthesis occur?
on the ribosomes in the cytoplasm of the cell
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 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.

The antibiotic streptomycin prevents protein synthesis in prokaryotes Which cell component is the most likely target of this antibiotic?
Aminoglycosides such as streptomycin target protein synthesis. The antibiotic drug, streptomycin, was the first successful cure in the treatment of tuberculosis.
Where is DNA decoded onto in protein synthesis?
DNA is first transcribed into mRNA in the nucleus of the cell. This mRNA then moves to the cytoplasm, where it is translated by ribosomes. The ribosomes decode the mRNA sequence and synthesize the corresponding amino acids into a protein. Therefore, protein synthesis occurs in the cytoplasm.
