A stop codon on an mRNA molecule does not code for any?
A stop codon on an mRNA molecule signals the ribosome to stop translating the mRNA sequence into a protein. It does not code for any amino acid and instead marks the end of protein synthesis. The three stop codons are UAA, UAG, and UGA.
Do stop codon have an amino acid?
A stop codon (UGA, UAA, UAG) only codes for a stop. No amino acid results from a stop codon.
What happens if the amino acid STOP code is at the beginning or middle of a gene?
If this codon is a result of a mutation, the polypeptide will be prematurely terminated. The protein will be either non-functional and the organism will do without it, or the protein will become harmful to the organism.
What would happen if the ribosomes were not functioning?
If the ribosomes were not functioning, protein synthesis would stop and the cell would die. The proteins that are produced in the cell control the cell's activities and without them, basic life functions would cease.
If transport protein that carry amino acid into a cell stop working how might the process shown be affected?
it will kill the organs
What code tells a cell to stop making a protein?
The code for a cell to stop making a protein is a stop codon in the mRNA sequence. Proteins are synthesized by the ribosome until it encounters a stop codon (e.g., UAA, UAG, UGA), which signals the end of translation, leading to the release of the protein and dissociation of the ribosome from the mRNA.
What is the importance of stop and start codons in the process of protein synthesis?
Stop and start codons are crucial in protein synthesis because they signal the beginning and end of protein production. The start codon initiates the process of translation, while stop codons indicate when the protein is complete. Without these codons, the cell would not know when to start or stop making the protein, leading to errors in protein production.
What is the significance of the stop codon in E. coli's genetic code?
The stop codon in E. coli's genetic code serves as a signal to the cell to stop protein synthesis, ensuring that the protein is made correctly and functions properly. This helps regulate the process of gene expression and prevents the production of incomplete or faulty proteins.
How does the ribosome know how to stop making a protein?
It reaches one of the 3 possible stop codons on the mRNA: UAA, UGA, or UAG. These codons do not code for any amino acid, but instead cause the polypeptide release factor to cleave the newly made protein from the last tRNA. (ed. spelling - I mixed got my words up :)
How cell stop diffusion through protein channels?
by closing gates
What might happen to the stop codon in a frameshift mutation?
In a frameshift mutation, the stop codon may be altered or shifted, potentially leading to a change in the reading frame of the genetic code. This can result in the formation of a different protein or a longer protein than intended, affecting the normal functioning of the cell.
Is "aug" a stop codon in genetic code?
No, "aug" is not a stop codon in the genetic code. It is actually the start codon that signals the beginning of protein synthesis.
What is true about aminoglycoside drugs is correct a. stop protein production b. are antimetabolites c. stop cell wall production d. aminoglycoside drugs include penicillins?
stop protein production
What would result if ribosomes in a cell stopped working?
If ribosomes in a cell stopped working, protein synthesis would cease, leading to a lack of essential proteins needed for cell function. This would ultimately result in cell death and potentially disrupt overall cell function in the organism.
How do viruses cause cancer?
In your cell you have cancer suppressors such as the P53 or the ASP proteins that when they have genetic mutations of tumor cells they will stop the cell cycle. Viruses stop the Rb protein and the P53 so that the cell goes on creating "viral genetic code" like a normal virus does but doesn't know its causing cancer because the cell genome in unstable. cancer results.
A stop codon on an mRNA molecule does not code for any?
A stop codon on an mRNA molecule signals the ribosome to stop translating the mRNA sequence into a protein. It does not code for any amino acid and instead marks the end of protein synthesis. The three stop codons are UAA, UAG, and UGA.
What would be the most likely outcome if the ribosomes of a cell were damaged and stopped functioning?
If ribosomes in a cell were damaged and stopped functioning, protein synthesis would be disrupted. This could lead to a decrease in cell function, impaired growth and development, and ultimately cell death.
