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 first step of translation is called initiation. In this step, mRNA, a tRNA containing the first amino acid of the polypeptide, and two ribosomal subunits come together to start the process. The small subunit then binds to both mRNA and a specific initiator tRNA, which contains the amino acid methionine (MET).
