What are the 3 steps of the elongation of translation?
What are the 3 steps of the elongation of translation?
To see how cells make proteins, let’s divide translation into three stages: initiation (starting off), elongation (adding on to the protein chain), and termination (finishing up).
What are the steps of translation elongation?
During the elongation stage, the ribosome continues to translate each codon in turn. Each corresponding amino acid is added to the growing chain and linked via a bond called a peptide bond. Elongation continues until all of the codons are read.
What are the 5 steps of translation?
Translation (Protein Synthesis)
- Initiation. In this step the small subunit part of the ribosome attaches to the 5′ end of the mRNA strand.
- Elongation.
- Termination.
What is the correct order of the stages of translation?
The correct order of stages of translation is initiation, elongation and termination.
What are the 7 steps of translation?
Terms in this set (7)
- mRNA binds to the small subunit of the ribosome.
- tRNA with anticodon complementary to the first codon to be translated on the mRNA binds to the ribosome.
- a second tRNA with an anticodon complementary to the second codon on the mRNA then binds.
Which of these is the first step of translation elongation?
The ribosome has three sites for tRNA binding, designated the P (peptidyl), A (aminoacyl), and E (exit) sites. The initiator methionyl tRNA is bound at the P site. The first step in elongation is the binding of the next aminoacyl tRNA to the A site by pairing with the second codon of the mRNA.
What are the 5 steps of translation in order?
What is the process of elongation in DNA?
Elongation. During elongation, an enzyme called DNA polymerase adds DNA nucleotides to the 3′ end of the newly synthesized polynucleotide strand. This process will continue until the DNA polymerase reaches the end of the template strand.
What is elongation in transcription?
Basically, elongation is the stage when the RNA strand gets longer, thanks to the addition of new nucleotides. During elongation, RNA polymerase “walks” along one strand of DNA, known as the template strand, in the 3′ to 5′ direction.
What is the elongation stage of replication?
During elongation, a primer sequence is added with complementary RNA nucleotides, which are then replaced by DNA nucleotides. During elongation the leading strand is made continuously, while the lagging strand is made in pieces called Okazaki fragments.
What are the six steps of translation in eukaryotes?
Translation is executed in six steps: (i) binding of mRNA to ribosome, (ii) aminoacylation, (iii) initiation, (iv) elongation, (v) termination and (vi) post-translational modification, (i) Binding of mRNA to ribosome I. binding of mRNA to ribosome
What is the function of elongation?
Elongation factors are a set of proteins that are used in protein synthesis in the process of cell cycle and elongation in some cells.
What is the meaning of elongation?
elon·ga·tion | \\(ˌ)ē-ˌlȯŋ-ˈgā-shən \\. 1 : the angular distance in the sky between a celestial body and another around which it revolves or between a celestial body and a particular point (such as the point where its path intersects the horizon) the elongation of Venus from the Sun.
What is a translation factor?
In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.
