Energy Cost for Protein Synthesis

Since protein is the major constituent of any cell, growth regulation is closely related to the control of ribosome synthesis. In fact, the number of ribosomes per. Protein genes suggests that ribosomal protein synthesis may be regulated in. 1980, to control for differential loading of RNA on each gel lane. Because the. Ribosomal assembly requires three or four separate ribosomal RNA rRNA molecules as well as ~50–80 ribosomal proteins r-proteins; the exact numbers.

Animation of Protein Synthesis (Translation) in Prokaryotes

After translation, the protein passes into the channels of the rough endoplasmic reticulum (ER) for transportation. The protein is then passed from the rough ER to the Golgi apparatus inside tiny fluid-filled sacs, called vesicles. The Golgi apparatus is a system of , which are responsible for the modification, processing, and packaging of the proteins. The protein may have a carbohydrate added, to form a glycoprotein. The Golgi apparatus packages the protein in a secretory vesicle, which fuses with the cell membrane and releases the protein from the cell.

Replication occurs in the S-fase in preparation to cell division during which the genetic information for the synthesis of proteins is transfered from the mothercell to the daughtercell.

Internet-Based Tools for Teaching Transcription and Translation

Four major steps are required to initiate translation: ribosome dissociation, formation of a preinitiation complex, formation of the 40S initiation complex and formation of the 80S initiation complex.

where it directs the synthesis of the protein, ..

When a stop codon appears at the translation is terminated. There are no tRNA's that recognize stop codons. Instead proteins called releasing factors, eRF, recognize the stop codon. The releasing factors along with peptidyl transferases and GTP catalyze the hydrolysis of the bond between the polypeptide chain and the tRNA. The protein and tRNA disassociate from the site and the ribosome dissociates into the 40S and 60S subunits releasing the mRNA.

Virtual Lab: Protein Synthesis | Labster

During elongation the protein is synthesized one amino acid at a time on the 80S ribosome. This process occurs in three major steps: binding of charged tRNA, peptide bond formation, translocation of the growing peptide chain.
