THE OFFICIAL NORDSCHLEIFE LAP RECORD VIDEO! On 19 August 2009, Radical Sportscars from Peterborough, England, successfully smashed the NÃ¼rburgring Nordschleife Production Car Lap Record by eight seconds, with racing driver and âRing expert Michael Vergers at the wheel.
Now that weâve described DNA and RNA, itâs time to take a look at the process of protein synthesis. The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cellâs nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
The formation of the peptide bond consumes energy, which, in living systems, is derived from ATP. Polypeptides and proteins are chains of amino acids held together by peptide bonds. Living organisms employ enzymes to produce polypeptides, and ribosomes to produce proteins. Peptides are synthesized by specific enzymes. For example, the tripeptide glutathione is synthesized in two steps from free amino acids, by two enzymes: gamma-glutamylcysteine synthetase and glutathione synthetase.
