How is translation terminated?
Translation termination occurs when the ribosome encounters a stop codon (UAG, UAA, or UGA) in the A site. Stop codons in bacteria are recognized by RF1 and RF2: RF1 recognizes UAG and UAA codons, whereas RF2 recognizes UGA and UAA.
What is required for the process of translation?
The key components required for translation are mRNA, ribosomes, and transfer RNA (tRNA). During translation, mRNA nucleotide bases are read as codons of three bases. There are also specific codons that signal the start and the end of translation.
What typically terminates the process of translation?
No tRNA can recognize a stop codon. Translation termination concludes with the dissociation of the two ribosomal subunits and mRNA from each other.
Does termination of translation require energy?
Termination Translation of an mRNA by a ribosome ends when translocation exposes one of the three stop codons in the A site of the ribosome. This interaction causes release of the new polypeptide and the disassembly of the ribosomal subunits from the mRNA. The process requires energy from yet another GTP hydrolysis.
Which step in translation does not require energy?
So, the correct answer is ‘Peptidyl transferase reaction’.
Which steps in translation requires energy?
What steps of translation require energy to occur? Charging a tRNA with its appropriate amino acid, initiation, codon recognition, transloaction of the tRNA in the A site to the P site, and disassembly of the ribosome require energy.
What happens at the end of translation answers com?
The end result of transcription and translation are proteins.
What is the final product of transcription?
RNA
What is the difference of translation and transcription?
The translation is the process of protein synthesis where the information on RNA is expressed in the form of polypeptide chains. Transcription is the first step in gene expression. The translation is the second and final step of gene expression.
What is the process of translation and transcription?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
What occurs during translation but not during transcription?
Specific processes must take place within the cell for protein synthesis to occur. Which occurs during translation but not during transcription? An mRNA template is used to create an amino acid chain.
Which is not directly involved in translation?
During translation DNA is not directly involved in its process. DNA first gets transcribed to RNA to form the mRNA which then gets translated to form the amino acid chain. DNA is only used in the process of replication and transcription. In translation it has no direct role.
