GN 311 Study Guide - Midterm Guide: Nucleoside Triphosphate, Polyploid, Dna Supercoil
Document Summary
* radioactivity does not go to next generation. * we know dna to be b-dna which is 10 base pair long. * top of phosphate (cid:271)o(cid:374)ds to (cid:1007)(cid:859) (cid:272)a(cid:396)(cid:271)o(cid:374) of diffe(cid:396)e(cid:374)t (cid:374)u(cid:272)leotide. * base pai(cid:396) joi(cid:374)s to (cid:272)a(cid:396)(cid:271)o(cid:374) at (cid:1005)(cid:859) * diff (cid:271)etwee(cid:374) deo(cid:454)(cid:455)(cid:396)i(cid:271)ose a(cid:374)d (cid:396)i(cid:271)ose is la(cid:272)k of o i(cid:374) (cid:1006)(cid:859) spot. * midpoint at which half of dna is denatured. * what does mar stand for and what two things do they link. * what happe(cid:374)s with telo(cid:373)e(cid:396)e (cid:1007)(cid:859) end overhang. * if something has bp per turn>10 it is negative supercoiling, * if 10 base pairs per turn dna has less complete turns than regular dna would, then it is negatively coiled. * meshlson and stahl; taylor and hughes experiments. * m&s: found new strand by weigh (old one was heavier) * over time, the band was found higher (more new strands) * t&h: used radioactivity to label old dna parts.
