briefly describe the events in translation

Expert Solution

Translation is the process of protein synthesis and encoding of genetic information in mRNA. In translation, mRNA is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The ribosome helps in decoding by inducing the binding of complementary tRNA anticodon sequences to mRNA codons.

There are following three events of translation

1) Initiation: During initiation, the small ribosomal subunit binds to the start of the mRNA sequence. Then a tRNA molecule binds to the start codon of the mRNA sequence. The start codon has the sequence AUG and codes for methionine. Next, the large ribosomal subunit binds to form the complete initiation complex.

2) Elongation: During this stage, the ribosome continues to translate each codon in turn. Elongation continues until all of the codons are read. The ribosome then moves to the next mRNA codon to continue the process. It creates a chain of amino acid.

3) Termination: Termination occurs when the ribosome reaches a stop codon. The new protein is then released, and the translation stops.

What events bring about the termination of translation?

A. List the 3 stages of translation. B. Briefly describe what happens at each stage.

Place the following translation termination events into the order of their occurrence:

Place the following translation termination events into the order of their occurrence: 1. The release factor signals the release the nascent peptide from the P site tRNA. 2. Dissociation of the mRNA and the last deacetylated tRNA occurs from the ribosomal subunits. 3. Recognition of the stop codon by a release factor that binds in the A site. 4. Translocation of the ribosome along the mRNA to place a stop codon in the A site. A. 3, 4, 2,1 B. 1, 2, 3, 4 C.4,...

Put the following events in the order they occur during translation. One event is NOT part of translation, do NOT include it in your sequence. The finished polypeptide, mRNA, and ribosomal subunits separate. A peptide bond is catalyzed between the first and second amino acids. The ribosome moves so that the third codon is in the A site. A second tRNA with brings in the second amino acid. The small ribosomal subunit associates with the mRNA and moves to the...

Decide which sequence of events is most CORRECT for the initiation and elongation steps of translation in prokaryotic cells? (1) small ribosomal subunit binds to mRNA (2) initiator tRNA binds start codon on mRNA (3) active 70S ribosome is formed (4) translocation of ribosome (5) binding of second aminoacyl tRNA A. 2, 3, 1, 5, 4 B. 1, 2, 3, 5, 4 C. 2, 1, 3, 4, 5 D. 1, 2, 3, 4, 5 E. 1, 3, 2, 4, 5
