Document Summary

Nt = n02n = n02 t/g = n0 2kt; t = growth time n = # times ppn doubles g = doubling time k = 1/g = #gen/unit time. O > n > s = c ~ h = p. Allosteric inhibition: molecule attach somewhere else, changes active site. Exergonic: general release of energy (think exothermic spontaneous) Eukaryote transcription: dna(full) [transcription] mrna (full), add 5"cap [splice w/snrps] spliced transcript enzyme adds poly-a tail, mature rna done. Rnap i genes for large rna molecules in ribosomes. Rnap iii genes for t-rna & small rna molecules in ribosomes. Rnap ii & iii rna molecules rfound in snrnps. Promoter & operators bind to both strands of dna the direction will depend on the sequence in the 5" 3". Atp good e carrier(big e release) b/c: o-p charge repulsion is relieved, release pgroup = more entropy (arrangements) Note: not b/c lots of e in the bonds .
