What are the steps of elongation?
During elongation, amino acids are continually added to the line, forming a long chain bound together by peptide bonds. Once a stop codon reaches the ribosome, translation stops, or terminates. At termination, the polypeptide is freed from the ribosome, and tRNAs stop bringing the amino acids in.
How does translation elongation cycle occur?
During translation elongation, the ribosome ratchets along its mRNA template, incorporating each new amino acid and translocating from one codon to the next. The elongation cycle requires dramatic structural rearrangements of the ribosome.
What are the steps in the translation process?
There are three important steps to the process of translation. There’s a beginning step, called initiation, a middle step, called elongation, and a final step, called termination. These three words may sound familiar to you. The same terms are used in transcription to describe the steps involved in making the mRNA strand.
What are the steps in the translation of mRNA?
There’s a beginning step, called initiation, a middle step, called elongation, and a final step, called termination. These three words may sound familiar to you. The same terms are used in transcription to describe the steps involved in making the mRNA strand. But, here in translation,…
What are the steps of transcription in DNA?
Triplets are groups of three successive nucleotide bases in DNA. Codons are complementary groups of bases in mRNA. You can also walk through the steps of transcription in this link. Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure 2.
Where does translation take place in the cell?
Translation is a process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain. It occurs in the cytoplasm following transcription and, like transcription, has three stages: initiation, elongation and termination.
