Document Summary
General biology 1 (101-nya) lecture notes (lecture 8) Basic principles of transcription and translation: the information content of dna is in the form of specific sequences of nucleotides, the dna inherited by an organism leads to specific traits by dictating the synthesis of proteins. Ribosomal rna: transcription is the synthesis of rna under the direction of dna, translation is the synthesis of a polypeptide, which occurs under the direction of mrna. The genetic code is universal, it is used in every living organism. Transcription: transcription produces rna, one type of rna, messenger rna (mrna), directs the synthesis of proteins. In a eukaryotic cell, the nuclear envelope separates transcription from translation, this is not the case in prokaryotes: transcription occurs in 3 stages: initiation, elongation, termination, rna polymerase bonds the rna nucleotides as they base-pair along the. Like dna polymerases, rna polymerases can only assemble a polynucleotide in its 5" 3" direction.
