BIOL 1010U Lecture Notes - Lecture 4: Central Dogma Of Molecular Biology, Transfer Rna, Cell Nucleus
Document Summary
Nucleic acids encoding information and transcription - Chapter 3 (section 3. 3) retrieval of genetic information stored in dna: transcription (pages 58 to 63) Chapter 3 (section 3. 4) fate of the rna primary transcript (pages 63 to 66) Use the following wireframe outline to make notes on the content presented in lecture 4. Makes a single-stranded mrna copy of a sequence of dna nucleotides (genes) Uses complimentary bae pair language: translation. Takes instructions encoded in mrna copy and translates them into a new language (trna with amino acids) that can make a polypeptide chain (protein) 9/20/17: elongation, termination mrna transcripts drops off and is used in translation, describe step 1 initiation compare and contrast in prokaryotes and eukaryotes. Rna polymerase binds to promoter ( = specific dna sequence) Promotor indicated template strand and direction of mrna synthesis. Is initiated at a promotor sequence and ends at a termentator sequence. Transcript is synthesiszed n a 5" to 3" direction.
