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.
This uses an mRNA sequence as a template to guide the synthesis of a chain of amino acids that form a protein. Translation proceeds in four phases: activation, initiation, elongation, and termination (all describing the growth of the amino acid chain, or polypeptide that is the product of translation).longation of the polypeptide chain involves addition of amino acids to the carboxyl end of the growing chain. The growing protein exits the ribosome through the polypeptide exit tunnel in the large subunit .In prokaryotes, three elongation factors are required for translation: EF-Tu, EF-Ts, and EF-G.
