DNA and Protein Synthesis - BioTopics

The of a protein depends on its rate of synthesis and its catalytic activity.ORb.

Control of protein synthesis ..

When protein synthesis, folding and processing, and trafficking occur properly, fully functional CFTR proteins reach the cell surface in sufficient quantity to maintain adequate ion transport.1-3,5

Redox signaling between DNA repair proteins for efficient lesion detection

Protein synthesis (DNA transcription, translation and | …

PURExpress® is a reconstituted protein synthesis system based on the PUREsystem™ (Shimizu et al., 2001) where all necessary components needed for in vitro transcription and translation are purified from E. coli.

The modified ends may promote the export of mRNA from the nucleus, and they help protect the mRNA from degradation.
RNA Splicing
The removal of large portions of the RNA molecule that is initially synthesized.


May 08, 2006 · Protein Synthesis: Transcription and ..

D. The nitrogen bases in double helical DNA are reversibly crossed linked by covalent bonds and these cross links are removed when regulatory proteins bind thus allowing strand separation and the initiation of transcription.

Translation: Making Protein Synthesis Possible - …

The three codons, UAA known as ochre, UAG as amber and UGA as opal, that do not code for an amino acid but act as signals for the termination of protein synthesis.
Stop Codon
Transcription Factor
A regulatory protein that binds to DNA and affects transcription of specific genes.

The authors note that the detailed studies of the molecular mechanisms of DNA repair pathways were made possible by using site-specifically modified oligonucleotides and that the availability of phosphoramidites to synthesize oligonucleotides with DNA lesions has contributed to the field. They illustrate the article using primarily structural studies in the following examples:

Protein Synthesis: Transcription & Translation

The polypeptide is thus freed from the ribosome.
The two ribosomal subunits and the other components of the assembly dissociate.
Final Folding
During its synthesis, polypeptide chain begins to coil and fold spontaneously as a consequence of its amino acid sequence (primary structure), forming a protein with a specific shape.

Protein Synthesis: Transcription & Translation ..

The CFTR protein reaches the apical epithelial cell membrane as part of a multistep process. As with all protein, this process involves synthesis ( and ), folding and processing, to their destination (e.g., ), and .1-4

Protein synthesis is process by ..

1. Discuss the three roles of RNA in protein synthesis. Name each type of RNA molecule and briefly describe its function. Then draw a diagram indicating where these three molecules fit into the process of protein synthesis.
