Protein synthesis can be stopped by blocking translation, primarily by inhibiting the functions of ribosomes or tRNA molecules in the cell. For example, antibiotics like puromycin can prematurely terminate protein synthesis by mimicking the structure of aminoacyl-tRNA and binding to the A site on the ribosome. Additionally, certain drugs or compounds can target key components of the translation machinery to halt protein synthesis.

What is the protein synthesis termination triplet?
The protein synthesis termination triplet is the stop codon found in mRNA that signals the end of translation. The three stop codons are UAA, UAG, and UGA. When a ribosome encounters a stop codon, it signals the release of the newly synthesized protein.
Why is it important that a signal to stop translation be part of protein synthesis?
They signal to stop protein synthesis and release the amino acid chain. Stop codons are important because they signal the end of synthesis. Sometimes, mRNA is longer than what is needed for the amino acids so without stop codons, synthesis would continue until the end of the strand of RNA, leaving you with an incorrect amino acid chain.
Synthesis of a protein stops when?
Synthesis of a protein stops when a stop codon is reached on the mRNA during translation. This signals the ribosome to release the newly synthesized protein so it can fold into its functional structure.
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.
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.
What codons stop protein synthesis?
The codons that signal the termination of protein synthesis are known as stop codons. In the genetic code, there are three stop codons: UAG, UAA, and UGA. When a ribosome encounters one of these codons during translation, it signals the end of protein synthesis and the release of the completed protein.

What is the product of protein synthesis?
A protein. That's what protein synthesis means.
What terminates a growing protein chain?
A stop codon on the mRNA sequence signals the termination of protein synthesis, causing the release of the completed protein from the ribosome.
The termination codons that serve as stop signals for the protein synthesis is called?
The answer is "Non-sense" codons
What is the role of rRNA the protein synthesis?
it hold the protein synthesis in the ribosomes
Structure responsible for protein synthesis?
Ribosomes, are responsible for protein synthesis.
What is the center of protein synthesis?
Ribosomes play important role in the protein synthesis.
What do the ribosomes job?
They provide surface for protein synthesis. They are the sites of protein synthesis.
