Which of the following are involved in elongation of translation?
The three steps for the elongation process of translation are codon recognition, peptide bond formation, and translocation. These steps essentially correspond to the different tRNA positions in the ribosome. tRNA enters and matches the codon of the mRNA strand.
What is elongation in biology 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 happens during the elongation step of DNA transcription quizlet?
What happens during the elongation step of DNA transcription? RNA polymerase moves along the template strand of the DNA creating an mRNA strand.
Which of the following best describes the Translational elongation process?
Which of the following BEST describes the translational elongation process? tRNA molecules condense with rRNA molecules. Ribonucleotides are added to amino acids through the synthesis of phosphodiester bonds. The polypeptide chain is lengthened by synthesizing peptide bonds between amino acids.
What is elongation in translation?
Extending the chain: Elongation Elongation is the stage where the amino acid chain gets longer. In elongation, the mRNA is read one codon at a time, and the amino acid matching each codon is added to a growing protein chain.
What happens during elongation in DNA replication?
During elongation, an enzyme called DNA polymerase adds DNA nucleotides to the 3′ end of the newly synthesized polynucleotide strand. The template strand specifies which of the four DNA nucleotides (A, T, C, or G) is added at each position along the new chain.
What happens during the elongation phase of translation?
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 transformation occurs during each of the processes translation?
During translation, an mRNA molecule is transformed into a polypeptide, which will eventually become a protein.
What is the elongation of translation?
Translation elongation is a key step of protein synthesis, during which the nascent polypeptide chain extends by one amino acid residue during one elongation cycle. More and more data revealed that the elongation is a key regulatory node for translational control in health and disease.
What is elongation stage?
Elongation is the phase of the protein-synthesis pathway that is responsible for the growth of nascent polypeptide chains. The two-site model postulates that the ribosome has two sites for transfer RNA (tRNA) binding: one that binds aminoacyl-tRNAs preferentially and a second that is specific for peptidyl-tRNAs.
What happens during transcription elongation?
Definition. Transcription elongation is a regulated process in which an RNA chain complementary to the template strand of DNA is synthesized as RNA polymerase moves along DNA. Transcription elongation is preceded by transcription initiation and is followed by transcription termination.
What happens during translation in biology?
In biology, the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). The mRNA is made by copying DNA, and the information it carries tells the cell how to link amino acids together to form proteins.
