Unformatted text preview: sequence of DNA, unwinds DNA & assembles DNA strand of RNA nucleotides transcription in a Eukaryotic cell, transcription of RNA from DNA takes place in the nucleus RNA must then travel through pores in the nuclear membrane to the cytoplasm, where translation of RNA to proteins will occur 1) messenger RNA – this long strand of RNA is clamped between large & small subunits of ribosomes; tRNA brings amino acids to the mRNA according to its codon sequence th it 2) transfer RNA – one end contains anticodon which pairs with mRNA codon; other end brings the appropriate amino acid 3) ribosomal RNA – a ribosome is a complex of RNA & protein ribosomes are found on the rough Endoplasmic Reticulum and in the cytosol (thus both are sites of protein synthesis) translation (like transcription, is divided into three stages) initiation elongation tRNA brings Met (methionine) in response to start codon (AUG) on mRNA termination large ribosomal subunit binds to small subunit ribosomal subunit binds to small subunit read...
