Translation / Protein Synthesis

The process of synthesizing protein using RNA as a template is known as translation.

Translation: Making Protein Synthesis Possible - …

Similar to TnaC described above, the peptide SecM exists solely to stallthe ribosome synthesizing it. But unlike TnaC, which also requires thepresence of high levels of trytophan, SecM has an intrinsic stallingcapability. Stalling of the ribosome synthesizing SecM provides time fora downstream RNA helix on the same mRNA strand to unwind. Unwinding ofthis helix then allows for a new ribosome to bind and synthesize anew protein, SecA, a bacterial ATP-driven translocase that aids the passage ofnascent proteins across membranes in conjunction with SecY (see also ). When sufficient levels of SecA have been reached,SecA interacts with the SecM-stalled ribosome to pull on SecM, freeingit and allowing translation to resume (illustrated schematically inFig. 13). SecM, which serves no otherpurpose than to stall the ribosome, is released into the cell anddegraded.

Complex of mRNA, and ribosomes is often called polisome."Protein Synthesis.

RNA translation, and protein synthesis.

It acts as a central regulator of many biological processes that are essential for cell proliferation, angiogenesis, and cell metabolism.1-3 mTOR exerts its effects primarily by turning on and off the cell's translational machinery, which includes the ribosomes, and is responsible for protein synthesis.

It synthesizes protein of interest using wheat germ cell-free system and through bi-layer reaction.

Translation- the process by which a specific gene's genetic information is rewritten into an RNA molecule.
Transcription- The making of proteins (Postlethwait 2009).
There are three main types of RNA that play different roles in protein synthesis (Postlethwait 2009).
Th first is messenger RNA or mRNA.

Innovative and fun way of presenting protein synthesis."This video shows bunch of people ...


Ribosome feedback regulation, and growth rate-dependent controls of rRNA synthesis remain to be determined despite numerous investigations. r-protein. REGULATION OF RIBOSOMAL PROTEIN SyNTHESIS. control of ribosomal synthesis can be considered in relation to three basic problems 75.

Transfer RNA transfers amino acids used to make proteins to the ribosomes (Postlethwait 2009).
First, an enzyme that catalyzes the formation of RNA on a template of DNA called RNA polymerase, binds to a promoter ( a nucleotide sequence of DNA where RNA binds and starts transcription) and separates the two strands of DNA (Postlethwait 2009).

In E. coli, most ribosomal protein r-protein synthesis is coordinated with. control mechanisms to the regulation of r-protein synthesis, we. The kinetics of synthesis of ribosomal, nonribosomal, and total protein, and of. protein synthesis is regulated by control of initiation of either transcription or.

Time-saving video on protein synthesis

When it finds the start sequence AUG, the codon (triplet) for the amino acid methionine, the large subunit joins the small one to form a complete ribosome and the protein synthesis is initiated.

A new tRNA+amino acid enters the ribosome, at the next codon downstream of the AUG codon.

Protein Synthesis (transcription & translation) ..

Where the RNA releases both the newly formed RNA and the DNA (Postlethwait 2009).
There are five steps in translation.
During step one (known as initiation) tRNA carrying methonine, and mRNA join together (Postlethwait 2009).
