What happens when translation is complete?
Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. Since there are no tRNA molecules that can recognize these codons, the ribosome recognizes that translation is complete. The new protein is then released, and the translation complex comes apart.
What is the ending material of translation?
How is Translation Different from Transcription?
| Transcription | Translation | |
|---|---|---|
| Template | DNA | mRNA |
| End Product | RNA | Protein |
| Location (eukaryotes/prokaryotes) | Nucleus/cytoplasm | Endoplasmic reticulum/cytoplasm |
| Controlling Factor | RNA polymerase | Ribosomes |
What is the last stage of translation called?
termination
The final stage of translation is termination. The signal to stop adding amino acids to the polypeptide is a stop codon (UAA, UAG, or UGA), for which there is no partner tRNA. Rather, special proteins called release factors bind to the A site of the ribosome and trigger an enzymatic reaction by the ribosome.
What is the product or end result of translation?
The molecule that results from translation is protein — or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.
What is the end product of the DNA?
The central dogma states that the pattern of information that occurs most frequently in our cells is: From existing DNA to make new DNA (DNA replication?) From DNA to make new RNA (transcription) From RNA to make new proteins (translation).
What is the end product of replication?
What is the end product of replication? Two identical DNA strands. Each one is made of one original strand and one new strand.
What does translation end with?
Translation ends in a process called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. Stop codons are recognized by proteins called release factors, which fit neatly into the P site (though they aren’t tRNAs).
At which end of mRNA translation always begins?
Translation begins when a start codon is recognized in the mRNA molecule. The start codon is AUG, which codes for the amino acid methionine; therefore, all proteins begin with methionine. There are multiple stop codons; therefore, the ending of proteins could be different from one another.
