Document Summary

Describe basic mechanism of transcription in prokaryotes and eukaryotes. Identify how rna polymerase creates rna transcript from dna template. Explain how compartmentalization of eukaryote cells allows for transcription and functional maturation of mrna prior to translation in cytosol. Dna has genes that code for proteins / rna molecules > various cell functions. Genes: sections of dna which contain info that is transcribed into rna copy, mrna further interpreted through translation > makes proteins. Process of copying and interpreting genes into proteins. Francis crick in 1950: central dogma > info in dna will specify sequence of bases in rna molecule. Gene expression: transition from dna > mrna > protein (requires transcription from dna . Dna > has deoxyribose sugar, has thymine, double stranded. Rna > has ribose sugar, has uracil, single stranded. Only one strand is the template strand (the one which will transcribed) Rna is complement of dna template strand.
