Translation Animation 2 - translation elongation in prokaryotes - This video lecture explains about the elongation of protein synthesis in prokaryotes. Once translation initiation is complete elongation begins the elongation phase consists of three steps binding of a tRNA to the ribosome formation of a peptide bond between adjacent amino acids and movement of the ribosome to the next codon elongation continues one: a time and the start codon is reached as initiation concluded that tRNA was hydrogen bonded to AUG in the piece side of the ribosome next codon is in the a site in this case the codon's UCC which encodes serine is bearing tRNA in the cytoplasm is a complex with the elongation factor TU and GTP this serial tRNA EF TU GTP complex enters the inside with a tRNA anti-codon was hydrogen bonds with the UCC codon upon binding the GTP is hydrolysed and DEF TU is released and recycled with a tRNA in both the P and a cites a peptide bond can form between adjacent amino acids this reaction is catalysed by peptidase transferase residing in the wild ribosomal subunit first step involves breaking the bond between Matt and its tRNA in the piece site next a peptide bond is between the now freed as Matt on the serine which is attached to its tRNA in the a site peptide bond formation is a condensation reaction that results in the release of water at one time it was thought that peptidase transferase was an enzymatic protein however more recently it was discovered that peptidase transferase is a catabolic RNA molecule and RNA capable of catalysing a reaction is called ribozyme is the peptide bond has formed the remains and an charged tRNA in the piece site and a tRNA with the growing polypeptide chain in the site the ribosome now moves one codon along the mRNA with the help of EFG and another GTP EFG GTP complex binds to the ribosome hydrolysis of GTP occurs and translocation began is an charged tRNA moves from the insight into the east side blocking the next amino ACL tRNA from attaching to the a side until translocation is complete tRNA in the a side still bound to it: now moves into the piece site once this tRNA is bound correctly in the piece side of the charged tRNA is rejected from the ease site site is now open for the next amino ACL tRNA to enter allowing the elongation process to continue an average polypeptide consists of about 300 amino acids let's watch the elongation process once again. • Thank You for watching our videos from Biology Animation Videos channel. This channel is created to compile animated biology lectures and videos from different animation sources. None of these videos are created by us. we just organize them and place them in YouTube for your understanding so If you want to know details about these animation please see the credit section for knowing the original content developer and please convey privilege and gratitude to them.
