When the ribosome reaches a nonsense codon, which of the following occurs?

a methionine is incorporated
the polypeptide is released
a peptide bond forms
the A site binds to a charged tRNA

Respuesta :

Answer:

The correct answer will be option-the polypeptide is released.

Explanation:

The non-sense codons are the codons which do not have any t-RNA thus do not code for any amino acids and leads to the termination of the translation.

The main non-sense codons are UGA, UAA and UAG which when read by the ribosome terminates the process of translation as these codons do not have the t-RNA due to which the ribosome releases the polypeptide from the E-site of the ribosome and terminates the process.

Thus, the option-the polypeptide is released is the correct answer.

The study of DNA is called genetics. There are two types of genetic material and these are DNA and RNA.

The correct answer is option B that is the polypeptide is released.

What is a ribosome?

  • The ribosome is the organelles that help information through the protein through the amino acid.

The non-sense codons are the codons that do not have any t-RNA thus do not code for any amino acids and lead to the termination of the translation.

The main non-sense codons are UGA, UAA, and UAG which when read by the ribosome terminate the process of translation as these codons do not have the t-RNA due to which the ribosome releases the polypeptide from the E-site of the ribosome and terminates the process.

Thus, the option-the polypeptide is released is the correct answer.
