The 5 Steps of Protein Synthesis Flashcards | Quizlet

(Type I and type II synthetases, respectively.) Even if the amino acid is initially attached to the 2' OH, it is the 3' OH form that is used in protein synthesis.* This charged tRNA is now ready to take part in translation.

When the mRNA stop codon is reached, the fully synthesized protein does not simply fall off the ribosome. Release factors (RFs) are the protein assistants that recognize the presence of a stop codon in the ribosomal A-site and trigger cleavage of the polypeptide from the P-site tRNA (Fig. 9). In prokaryotes, RF1 hydrolyzes the protein […]

The heart of protein biosynthesis lies in the elongation cycle, with its sequential decoding of mRNA codons to assemble the useful portion of the polypeptide. Elongation can be further broken down into three phases— aminoacyl-tRNA decoding, peptide bond formation, and translocation of the new peptidyl-tRNA (Fig. 7). A. Decoding According to Base Pairing Comparison of […]

Following release of the synthesized protein, the ribo-some contains an empty tRNA in the P-site or E-site, and mRNA is still bound with the stop codon in the A-site. This arrangement of components is the post-termination complex. A protein known as the ribosome recycling factor (RRF) promotes the dissociation of this complex in preparation for […]

The resulting aminoacyl-tRNAs (AA-tRNAs) are transported by the elongation factor (EF-Tu in bacteria and EF1A in archaea and eukaryotes) to the ribosome as building blocks for protein synthesis [2,3].

The Seven Steps Of Protein Synthesis
Step One
DNA gets a signal that a particular protein needs to be made and unzips the part of the code.
Step 6
At every 3 base pairs, t RNA attaches a particular amino acid for the particular DNA
Step 7
Once the code has been completely read, a stop signal is given and protein synthesis is complete and the protein goes where it is needed

The process of polymerization of amino acids to form a polypeptide is called as Translation. It is the second and final step of protein synthesis. The order into which the amino acids are arranged is defined by the bases in mRNA (messenger). Ribosome is the cellular factory responsible for the protein synthesis. The ribosome consists of structural RNAs and about 80 different . It is in inactive stage and exists as two subunits, one large and other small. The synthesis of begins when the small subunit encounters an mRNA. The ribosome also acts as a catalyst for the formation of bonds.

Protein Synthesis Steps Protein Synthesis Steps In Brief

The process of copying of the genetic information from one strand of DNA into RNA is termed as transcription. This is the first step required for synthesis. Transcription is also based on the complementarity of the strand. Also, only one strand of the DNA is converted into . One transcription unit consists of 3 regions: A promoter, the Structural Gene and a Terminator. The promoter is located towards the 5’ end and defines the template and coding strand. The terminator is towards the 3’ end defining the end of transcription process. The is transcribed in 5' to 3’ direction by polymerase.

Initiation of protein synthesis requires assembly of the ribosomal subunits, messenger RNA, and initiator tRNA at the start codon. This organization of translational components is facilitated by protein initiation factors (Fig. 5). FIGURE 5 Translation initiation. In prokaryotes, three initiation factors are responsible for assembling the initiation complex prior to decoding of a message. The […]

The amino acids are joined to form proteins by peptide bonds. The formation of peptide bonds requires a good amount of energy. Therefore, in the first phase of translation for protein synthesis, the amino acids are activated in the presence of ATP and linked to their cognate tRNA (transfer RNA). This process is called as charging of the tRNA or aminoacylation of tRNA. If two such charged tRNA are brought close enough, the formation of peptide bond between them is favored energetically. This function occurs inside the , as it contains two sites for subsequent amino acids to bind to and thus be close enough for bonding.
